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?

  • chemistry -

    I know the molecular weights of the acids:

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

  • chemistry -

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

  • chemistry -

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