Answer:
Option A
Explanation:
As we know
Percent yield is the ratio of actual yield/theoretical yield
a) Percent yield - Theoretical yield 52.3 g; actual yield 50.7g = 0.97 = 97%
b) Percent Yield - Theoretical yield 17.1 g; actual yield 15.7g = 92%
c) Percent Yield - Theoretical yield 38.8 g; actual yield 36.2 g = 93%
d) Percent Yield - Theoretical yield 24.6 g; actual yield 22.5 g = 91%
Hence option A is correct
