Question

When 59.8 g of calcium is reacted with nitrogen gas, 25.6 g of calcium nitride is produced. What is the percent yield of calcium nitride for this reaction? 3Ca(s)+N2(g)→Ca3N2(s)

Answer 1

let ex be the mass of (az No produced by 59.8 g of la. 3x uog of a gives 1489 of (a3N2. 59.89 of a gives - x Cross multiply 3X40 X X= 148*59.8 148 X 59.8 X - 3840 x = 73.75339 = theoretical yield Actual yield = 25.69. % yield= x 100 Actual theoretical 25.6 . X 100 73.7533 = 34.710 29 %.
