a) The molar mass of trans-[Co(en)2Cl2]Cl is 299.42 g/mol and there were 0.0096375 moles available in the starting solution. b) The theoretical yield of the product is 2.8843 grams. c) The percent yield of the product is 42.21%.
a) The molar mass of trans-[Co(en)2Cl2]Cl is calculated by summing the atomic masses of all the atoms in the compound. The atomic masses are as follows: Co = 58.93 g/mol, en = 59.07 g/mol, Cl = 35.45 g/mol. Therefore, the molar mass of trans-[Co(en)2Cl2]Cl is 58.93 + 2(59.07) + 2(35.45) + 35.45 = 299.42 g/mol. The number of moles available in the starting solution can be calculated using the formula: moles = volume (in liters) × molarity. Converting the volume from milliliters to liters and substituting the values into the formula gives: moles = 7.71 mL / 1000 mL/L × 1.25 mol/L = 0.0096375 mol.
b) The theoretical yield of the product can be calculated using the formula: theoretical yield (in grams) = moles of product × molar mass of product. The number of moles of product is 0.0096375 mol. Substituting the molar mass of trans-[Co(en)2Cl2]Cl from part a into the formula gives: theoretical yield = 0.0096375 mol × 299.42 g/mol = 2.8843 g.
c) The percent yield of the product can be calculated using the formula: percent yield = (actual yield / theoretical yield) × 100. Substituting the values into the formula gives: percent yield = (1.217 g / 2.8843 g) × 100 = 42.21%.
