31.5 grams of product were actually produced.

The percent yield is the percent of the theoretical yield that was actually yielded in an experiment, so the answer would be 75% of 42.0 grams of product ( 31.5 g ).

42.0 * 75% = 31.5

75% = 0.75   ( in decimal form, used for calculations )

Amount of grams were actually produced is 31.5 gram

Given that;

Theoretical yield of a reaction = 42.0 grams

Percent yield = 75%

Find:

Amount of grams were actually produced

Computation:

Amount of grams were actually produced = Theoretical yield of a reaction × Percent yield

Amount of grams were actually produced = 42 × 75%

Amount of grams were actually produced = 31.5 gram
