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

Do you have any densities?

I know the molecular weights of the acids:
HCl  36.5
H2SO4  98.0
H3PO4  98.0 
I know the molar masses too. What we need is the density of each solution.

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