Question

A 3.0 L solution contains 73.5 g of `H_2SO_4`. What is the molar concentration of the solution?

Answer 1

Approx. `0.250*mol*L^-1`.

Explanation:

`"Concentration"=((73.5*g)/(98.08*g*mol^-1))/(3.0*L)=0.250*mol*L^-1`

The concentration is quoted with respect to `H_2SO_4(aq)`. What is the concentration with respect to `H_3O^+`, and why do I make this distinction?
