    Question: 3.175g of crystals heated until no furtherloss in mass. Anhydrous salt had a mass of 2.086g. How many moles of zincsulphate are there in 2.086g of anhydrous zinc sulphate ?

    This is my working: 3.175 - 2.086 = 1.089
    Moles = Mass/Mr
    1.089g/161.47g/mol-1 = 0.01 mol

    Is this correct ?
