Question

A sulfuric acid solution that is 65.0% H2SO4 by mass has a density of 1.55 g/mL at 20°C. What is the mass of h2so4 per liter of solution?

Answer 1

Mass of 1 L of solution = 1.55 g/mL * 1000 mL/L
= 1550 g/L

Percentage of H2SO4 by mass
= 65%

Mass of H2SO4 in 1 L
= 1550 g/L * 0.650
= 1007.5 g
= 1.01×10³ g approximately.
