## Homework Statement

Find the volume of 0.1M of Na2CO3 nH20 with a molar mass of x (x was given in midterm just not sure what it was)

C

_{m}=0.1M

M (Na2CO3 nH20) = x

V= ?

## Homework Equations

n=m/M

C

_{M}= n/v

## The Attempt at a Solution

I figured with the molar mass of the entire hydrate given I would subtract that from the molar mass of the anhydrate then divide that by the molar mass of water, 18, in order to find out the coefficient for H2O. But from here I got stuck as I seemed to be missing another variable in order to calculate either the mass or number of mols in the hydrate.
