there are 159.6g of cupric sulfate and 90.1g of waters63.5gCu+32.1gS+(16.0*4)gO=159.6gCuSO4 5(1.01*2)gH+5(16.0)gO=90.1g5H20

therefore, the gram formula mass is 249.7g

the percent composition of water is 36.1%((90.1g)/(249.7g))*100%

p.s.-my basic math skills suck so you may want to take the given values and crank them through the equation to check

Your math is correct. I ran the problem myself and got the same answer. We even did this as a lab in Chemistry class and I got near the same answer (35% in an unregulated test).

CuSO4 x5H20 is the molecular formula for cupric sulfate pentahydrate. Its molecular weight of 247.9 grams per mole. Also, the molecular weight of water is 18.02 grams per mole. The molecule is a pentahydrate, meaning it has 6 waters. This means 108.1 grams of each cupric sulfate pentahydrate is composed of water. 90.1 grams of water divided by the total mass of 249.7 equals .36. The answer then is 36% water.

The molar mass of Na2CO3 is 105.988 g/mol. The molar mass of H2O is 18.0153 g/mol. The total weight of the compound then is 286.141 grams. Water then comprises 62.96 percent of the compound.

What kind of compound is Na2CO3 x 10H2O?

Technically it is a mixture called a hydrate. This particular one is sodium carbonate decahydrate.


Why only 10H2O in sodium carbonate deca hydrate?

Sodium carbonate decahydrate is the name of the compound Na2CO3·10H2O, because 'deca' means 'ten'.The term hydrated sodium carbonate is commonly used to encompass the monohydrate (Na2CO3·H2O), the decahydrate and the heptahydrate (Na2CO3·7H2O).Both the hepta- and the decahydrate are partially transformed into the monohydrate thermonatrite Na2CO3·H2O when left over in dry air.Anhydrous (no H2O) sodium carbonate (Na2CO3) is formed when heating Na2CO3·H2O or NaHCO3 or Na3H(CO3)2·2H2O (trona) up to 150o-200oC (this is called calcination).
