An aqueous solution of sulfuric acid has a composition of 25.0 wt% sulfuric acid and a specific gravity of 1.22. calculate the volume of solution that contains 245 kg of sulfuric acid.

The volume of solution is

Explanation:

The relationship between specific gravity and density of a substance is given as:

Specific gravity of sulfuric acid solution = 1.22

Density of water = 1.00 g/mL

Putting values in above equation we get:

We are given:

25% (m/m) sulfuric acid solution. This means that 25 g of sulfuric acid is present in 100 g of solution

Conversion factor:  1 kg = 1000 g

Mass of solution having 254 kg or 245000 g of sulfuric acid is calculated by using unitary method:

If 25 grams of sulfuric acid is present in 100 g of solution.

So, 245000 grams of sulfuric acid will be present in =

To calculate volume of a substance, we use the equation:

Density of solution = 1.22 g/mL

Mass of Solution = 980000 g

Putting values in above equation, we get:

Hence, the volume of solution is
