Question

10ml of H₂SO₄ is dissolved in 90 ml of water. Calculate mass by volume percentage of solution.

Answer 1

Given: 

Volume of H₂SO₄ = 10ml 

Density of H₂SO₄ = 1.84 g/ml 

Now, we know, 

Mass = Density × Volume 

= (10 ml × 1.84 g/ml) g 

= 18.4g 

Total volume of the solution= (10+90) ml 

= 100ml 

Mass by volume percentage = \(\frac{Mass\,of\,solution}{Volume\,of\,solution}\times100\)

\(=\frac{18.4g\times100}{100\,ml}\)%

= 18.4 %

Hence, the mass by volume percentage of the solution is 18.4 %
