Question

I have no idea how to begin solving these problems...

Calculate the normality of a 1.0 molal solution of each of the following acids:
a. HCl
b. H2SO4
c. H3PO4

Calculate the molality of a 1.0 normal solution of each of the following acids:
a. HCl
b. H2SO4
c. H3PO4

Answer 1

Do you have any densities?

Answer 2

I know the molecular weights of the acids:

HCl -- 36.5
H2SO4 -- 98.0
H3PO4 -- 98.0

Answer 3

I know the molar masses too. What we need is the density of each solution.

Answer 4

I wasn't given any densities...except to assume that water has a density of 1.00 g/cm^3 in previous problems.
