A crystalline sample that has the formula MgCl 2.6H2O loses a portion of its water when it is dried in an oven for several hours but undergoes no other changes. If the student, Dora the Explorer, started with 10.000 g of the compound and ended up with a residue that weighed 7.342 g., what is the formula of the residue?
a) MgCl2.H2O
b) MgCl2.2H2O
c) MgCl2.3H2O
