After 0.6523g of CoCL2 .6H2O is heated, the residue has a mass of 0.3423g. Calculate the percent H2O in the hydrate. What is the formula of the hydrate

Answer 1

mass H2O in sample = 0.6523 - 0,3423 = ?
% H2O = (mass H2O/mass sample)*100 = ?

mols H2O = grams/molar mass = ?
mols CoCl2 = grams/molar mass = ?
convert to ?mols H2O/1 mol CoCl2 and formula will be CoCl2.?H2O in 1 mol CoCl2.
