Answer:

0.0432 M

Explanation:

To find the new molarity, you need to (1) calculate the number of moles (using the molarity ratio), then (2) calculate the new volume, and then (3) calculate the new molarity. The moles in the first molarity is the same amount in the new molarity. The final answer should have 3 sig figs like the given number with the smallest amount of moles.

(Step 1)

95.00 mL / 1,000 = 0.095 L

Moles:

Molarity = moles / volume

0.157 M = ? moles / 0.095 L

0.0149 = ? moles

(Step 2)

250.0 mL / 1,000 = 0.25 L

New Volume:

0.25 L + 0.095 L = 0.345 L

New Molarity:

Molarity = moles / volume

Molarity = 0.0149 moles / 0.345 L

Molarity = 0.0432 M

If the mass water content of the clod was 18%, its particle density is 2.65 g/cm³ and paraffin's density is 0.89 g/cm³,the bulk density is 1.728 g/cm³.

The term density is defined as the ratio of mass of a unit volume of a material substance. The formula for density is d = M/V,

First, determine the mass of the dry soil particles by subtracting the mass of the water from the total mass of the clod and paraffin:

Mass of dry soil particles = Total mass - Mass of water

= 993 g - (0.18 x 885 g)

= 850.3 g

Then we can determine the volume of the dry soil particles by dividing their mass by their particle density as follows:

Volume of dry soil particles = Mass of dry soil particles / Particle density

= 850.3 g / 2.65 g/cm³

= 321.4 cm³

i.Now, calculate the bulk density of the soil:

Bulk density = Mass of dry soil particles / Total volume

= 850.3 g / 492 cm³

= 1.728 g/cm³

ii. We can find the volume of voids by subtracting the volume of dry soil particles from the total volume of the clod as follows:

Volume of voids = Total volume - Volume of dry soil particles

= 492 cm³ - 321.4 cm³

= 170.6 cm³

Now, we can calculate the void ratio:

= Volume of voids / Volume of dry soil particles

= 170.6 cm³ / 321.4 cm³

= 0.531 or 53.1%

(iii) We can find the volume of water by multiplying the mass of water by the inverse of its density:

Volume of water = Mass of water / Density of water

= 0.18 x 885 g / 1 g/cm³

= 158.7 cm³

Now, calculate the degree of saturation:

Degree of saturation = Volume of water / Volume of voids

= 158.7 cm³ / 170.6 cm³

= 0.93 or 93%

Thus, the bulk density is 1.728 g/cm³.

The standard deviation of the sample is 0.579, rounded to the correct number of significant figures.

To calculate the standard deviation of the sample, we need to follow these steps:

To find the mean, we sum up all the data points and divide by the number of data points. Let's calculate it:

(3.09 + 4 + 2.775 + 2.5 + 3.80) / 5 = 16.165 / 5 = 3.233

To do this, we subtract the mean (3.233) from each data point and square the result:

(3.09 - 3.233)^2 = 0.020049

(4 - 3.233)^2 = 0.586489

(2.775 - 3.233)^2 = 0.209025

(2.5 - 3.233)^2 = 0.537289

(3.80 - 3.233)^2 = 0.323329

To find the variance, we sum up the squared differences from step 2 and divide by the number of data points:

(0.020049 + 0.586489 + 0.209025 + 0.537289 + 0.323329) / 5 = 1.676181 / 5 = 0.3352362

To calculate the pH of a solution of NaOH (sodium hydroxide), we need to consider that NaOH is a strong base that dissociates completely in water, producing hydroxide ions (OH⁻).

Given:

Concentration of NaOH = 0.005 M

Since NaOH dissociates into one hydroxide ion (OH⁻) per molecule, we can determine the concentration of hydroxide ions in the solution, which will allow us to calculate the pOH. Then, we can convert the pOH to pH using the relationship: pH + pOH = 14.

1. Calculate the concentration of hydroxide ions (OH⁻):

The concentration of OH⁻ ions will be the same as the concentration of NaOH since NaOH dissociates completely.

Concentration of OH⁻ = 0.005 M

2. Calculate the pOH:

pOH = -log[OH⁻]

pOH = -log(0.005)

Using logarithm properties, we can determine the pOH value:

pOH = -log(0.005)

pOH = -(-2.301)

pOH = 2.301

3. Calculate the pH:

pH = 14 - pOH

pH = 14 - 2.301

pH ≈ 11.699

Therefore, the pH of a 0.005 M NaOH solution is approximately 11.699.

The pH of a 0.005 M concentration of NaOH ( sodium hydroxide ) solution is approximately 11.70.

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

From the formula;

pH = -log[ H⁺ ]

pOH = -log[ OH⁻ ]

pH + pOH = 14

Given that; the concentration of solution (molarity) ( OH⁻ ) is 0.005 M.

First, we determine the pOH.

pOH = -log[ OH⁻ ]

Plug in ( OH⁻ ) = 0.005

pOH = -log[ 0.005 ]

pOH = 2.30

Now, plug pOH = 2.30 into the above formula and solve for the pH:

pH + pOH = 14

pH + 2.30 = 14

Subtract 2.30 from both sides:

pH + 2.30 - 2.30 = 14 - 2.30

pH = 14 - 2.30

pH = 11.7

Therefore, the pH of the solution is 11.7.

Chemistry => Thermochemistry => Enthalpy

We have a material that is heated until it goes from a solid state to a liquid state, that is, it melts.

To calculate the total energy we will take into account two stages:

1. Corresponds to the energy needed to raise the temperature from 20°C to 660°C.

2. The energy needed to melt aluminum at a constant melting temperature (660°C).

We will need the following data that we can find in the literature:

Specific heat of aluminum = 0.896J/g°C

enthalpy of fusion aluminum = 0.322J/g

For stage 1. the energy required will be calculated with the following equation:

Where,

Q is the energy required to raise the temperature

m is the mass of the aluminum soda can, 14g

Cp is the specific heat of aluminum, 0.896J/g°C

T2 is the final temperature, 660°C

T1 is the initial temperature, 20°C

We replace the known data:

For stage 2 the energy required will be calculated with the following equation:

Where

Qm is the energy required to melt the aluminum soda can

m is the mass, 14g

deltaHm is the enthalpy of fusion aluminum,0.322J/g

The energy required will be:

So, the total energy will be the sum of both energies. So, we will have:

Answer: It would take 8.0 kJ to melt 1 aluminum soda can
