composition of water in a hydrate, we need to look at our equation. compare it to your experimental values you just obtained in lab. To calculate the percent In this exercise, we are going to calculate the percent composition of water in a hydrate and percent (%) composition = of water mass of water х 100 mass of entire hydrate For LINO3 3H20 (lithium nitrate trihydrate) we have to calculate the mass of each element. Nelice the three in front of the water will give us a total of six hydrogens and three oxygens. Li: 1 x 6.94 g/mol N: 1x 14.01 g/mol H: 6x 1.01 g/mol O: 3x 16.00 g/mol O: 3x 16.00 g/mol 19ot lo0 68.95 g/mol a bluow e 54.06 g/mol percent (%) composition = of water 3 H20 х 100 LINO, · 3H20 percent (%) composition = of water 54.06 g/mol х 100 (68.95 g/mol + 54.06 g/mol) percent (%) composition of water in LINO3 • 3 H20 = 43.9 % 1. Calculate the percent composition of water in the following hydrates: (show all work) ZnSO, 7H20 MgSO, 7H20 BaCl2 · 2H20 There are additional questions on the other side.
