Define what is the formula of the oxalic alumina

Reference no: EM13719692

Question- A sample of pure alumina hydrate was obtained from a bag of flame retardant. A 5.000g sample of the material is heated carefully in a vacuum oven until no more mass was lost from the sample. After heating, the final weight of the material was 3.2692 g. What is the formula of the oxalic alumina, Al2O3*X H20 (mol.wt. Al2O3 = 101.96)

Please illustrate me how work it out above problem
