Question

The density of 95% by mass of sulphuric acid is 1.84gmL-1
What is the molarity of H2SO4?

Answer 1

Any idea on how to convert it?

Answer 2

[(% x d) / MW] x 10 = Molarity
where % is =95 %
MW = molecular weight of H2SO4
d= density = 1.84

Answer 3

the 95% is by mass, so 100g of acid contains 95g of H2SO4. Use that, and the density, to convert to g/mL, then mol/L

Answer 4

Is it 0.18moldm-3?

Answer 5

I mean 0.018
