Question

What volume of 95% sulphuric acid (density
=1.85 g/cm3) and what mass of water must
be taken to prepare 100 cm3 of 15% solution
of sulphuric acid (density = 1.10 g/cm3 )?​

Answer 1

Answer: MARK ME AS BRAINLIEST

Explanation: Volume of the solution = 100 cm2

Density of the solution = 1.10 g/cm3

Therefore, Mass of 100 cm3 of solution = 100 x 1.10 g =110 g

The given solutions is 15%. Therefore, 100 g of solution contains 15 g of H2SO4

Then, mass H2SO4 in 110 g (100 cm3 ) of solution = 15/100 * 110 = 16.5gm

Mass of water in 110 g (100cm3 ) of solution = (110 - 16.5) g = 93.5 g
