Question

After some time, the ethanol concentration is 2 g l^-1 and 7.5 g l^-1 acetic acid is produced. Calculate the Observed yield.

(a) 0.94 g g^-1

(b) 0.95 g g^-1

(c) 0.92 g g^-1

(d) 0.96 g g^-1

This question was addressed to me in semester exam.

My doubt is from Yields in Cell Culture topic in portion Homogenous Reactions of Bioprocess Engineering

Answer 1

Correct answer is (a) 0.94 g g^-1

Easy explanation: Using a basis of I litre, the observed yield over the entire culture period is obtained from equation:
