If 1.50 g of H2C2O4 2H2O were heated to drive off the water of hydration, how much anhydrous H2C2O4 would remain?

Thank you! Please explain clearly.

• Chemistry -

H2C2O4.2H2O ==> H2C2O4 + 2H2O

mols H2C2O4.2H2O = grams/molar mass
mols H2C2O4 = same as the hydrated material.
g H2C2O4 = mols x molar mass H2C2O4.
