The mass of an empty evaporating dish is 42.48 g. A sample of the hydrate KAl(SO4)2 x XH2O is added to the evaporating dish. The total mass of the evaporating dish + hydrate is 48.16 g. The evaporating dish is then heated to drive off all the water. After the heating, the mass of the evaporating dish + dehydrated KAl(SO4)2 (molecular mass=258.20 g/mol) is 45.57 g. The value of the integer x is:?
