Question

A bottle of Sulphuric acid (H 2 SO 4 ) is labelled as 20% Solution. What is the mass by volume % of
the solution? explain it

Answer 1

Explanation:

Answer: Sulfuric acid will be 20.40% m/v of solution.

Explanation:

We are given 20% m/m sulfuric acid solution, which means 20 grams of sulfuric acid is present in 100 grams of the solution.

Now, to calculate the volume of the solution, we use the formula:

Density=\frac{Mass}{Volume}Density=

Volume

Mass

Density of the solution = 1.02 g/mL

Mass of the solution = 100 grams

Volume of the solution = ? mL

Putting values in above equation, we get:

1.02g/mL=\frac{100g}{Volume}1.02g/mL=

Volume

100g

Volume of the solution = 98.03mL

Now, to calculate percentage m/v of the solution, we divide the mass of solute by the volume of solution, we get:

\%m/v=\frac{20g}{98.03mL}=20.40\%%m/v=

98.03mL

20g

=20.40%

Hence, Sulfuric acid will be 20.40% m/v of solution.
