Answer 2

Calculating the Amount of 60% Sulfuric Acid Solution

To calculate the amount of 60% sulfuric acid solution that can be prepared by adding sulfuric acid to 0.16 kg of water, we can use the formula for calculating the concentration of a resulting solution when a solute is added to a solvent.

The formula for calculating the concentration of a resulting solution is:

C1V1 = C2V2

Where: - C1 = initial concentration of the solution - V1 = volume of the solution - C2 = final concentration of the solution - V2 = volume of the solvent

In this case, the initial concentration of the sulfuric acid solution is 100% (pure sulfuric acid), and the final concentration is 60% (60% sulfuric acid solution). The volume of water is given as 0.16 kg.

Using the formula, we can calculate the volume of 60% sulfuric acid solution that can be prepared.

Calculation

Let's calculate the volume of 60% sulfuric acid solution that can be prepared by adding sulfuric acid to 0.16 kg of water.

C1 = 100% V1 = ? C2 = 60% V2 = 0.16 kg

Using the formula C1V1 = C2V2, we can solve for V1:

V1 = (C2V2) / C1

Substitute the values:

V1 = (60% * 0.16 kg) / 100%

V1 = 0.096 kg

So, 0.096 kg of 60% sulfuric acid solution can be prepared by adding sulfuric acid to 0.16 kg of water.
