Question

A student obtained 1.57 g of product in a chemical reaction in the lab although she expected to produce 2.04 g of product. What was the percent yield of the experiment?

A. 23.1%
B. 43.4%
C. 56.5%
D. 77.0%

Answer 1

D. 77.0%

Step-by-step explanation:

% yield = actual yield/theoretical yield x 100%

% yield = 1.57 g / 2.04 g x 100%

% yield = 76.96 (round up)
