Question

Answer the following question using the data:

A = 85 g/mol

D = 6 g/mol

E = 10 g/mol

G = 74 g/mol

J = 23 g/mol

L = 1 g/mol

M= 36 g/mol

Q = 24 g/mol

R = 87 g/mol

T= 50 g/mol

U = 20g/mol

Z = 44 g/mol

1. D9G8E4 can be synthesized/made from D7G6E3 and D4G6E3. In an experiment, a chemistry student produces 12.2 g of D9G8E4 using this reaction:

D7G6E3 + D4G6E3 = D9G8E4 + GD2G3E2

a) The student determines the percentage yield to be 72%. What was the theoretical yield (in grams)?

b) Considering the theoretical yield, what mass of D7G6E3 must have been present initially assuming D4G6E3 is in excess?
