If you mean hydrate as in <em>MgSO4 · 7H2O, </em>then simply find the molar mass of each element you see.
For the example above, that means you would add the molar mass (found on the periodic table) of Mg, then S, then 4(O), 14(H), and 7(O).
The results would be your molar mass for the hydrate.
I hope this is what you meant by your question!

Explanation:
Hello,
In this case, for the mole fraction of methanol we use the formula:

Thus, we compute the moles of both water (molar mass 18 g/mol) and methanol (molar mass 32 g/mol):

Hence, mole fraction is:

Next, mass percent is:

And the molality, considering the mass of water in kg (0.185 kg):

Regards.
Answer:
Hope this helps
molar mass: 170.21 g/mol
