Question

Concentrated aqueous sulphuric acid is 98% H2SO4 by mass & has a density of 1.84 g/cc. What volume of

concentrated acid is required to make 5.0 litre of 0.500M H2SO4 solution.​

Answer 1

Explanation:

To make 5 liters, you need 0.5 moles/L x 5 L = 2.5 moles of H2SO4. Molar mass of H2SO4 is 98 g/mole. 2.5 moles x 98 g/mole = 245 g of H2SO4 needed. 1.84 g/ml (x ml) = 245 g and x = 133.15 ml needed, if it were pure, 100% H2SO4.
