SOLVED: The alum used in cooking is potassium aluminum sulfate hydrate, KAl(SO4)2 ·x H2 O . To find the value of x, you can heat a sample of the compound to drive off all the water and leave only KAl(SO4)2 . Assume that you heat 4.74 g of the hydrated compound and that it loses 2.16 g water. What is the value of x ? | Numerade

The concentration of sulfate in a sample of wastewater is to be determined by using gravimetric analysis. To a 100.0-mL sample of the wastewater, an excess of strontium nitrate is added, forming the insoluble strontium sulfate (183.7 g/mol) according to the balanced equation given below. The solid strontium sulfate is dried, and its mass is measured to be 0.3887 g. What was the concentration of sulfate in the original wastewater sample?SO42–(aq) Sr(NO3)2(aq) → SrSO4(s) 2NO3–(aq)a) 0.71
