The solution for Q37 seems be given in the picture you posted. The first step would be figure out what you don't understand

Evaporite minerals are sedimentary deposits that have precipitated from hot aqueous solutions. Therefore they almost invariably contain some water of crystallisation. For example, a very common evaporite mineral is hydrated gypsum, whose chemical formula is CaSO4. 2H2O. Therefore I would include in the gravimetric analysis an allowance for a certain amount of water.
