Below are the formulas of some hydrates. what is the mole ratio of salt to water?

Hydrate
Na2SO4.10H2O
Co(NO3)2.6H2O
Mo(NO3)2.5H2O
CaSO4.2H2O
(CaSO4)2.H2)

Thankk you

    There must be something about this that you don't understand. Tell me what it is and let's get these pesky problems out of the way. I did the mole ratio for ZnSO4.7H2O and told you it was 1 mole salt to 7 moles H2O, which follows from the formula (ZnSO4)1.7H2O. It's just a matter of looking at the formula and writing down the answer unless there is some hangup I don't know about.
