Enantiomeric excess (ee) is a measure used in stereochemistry to describe the purity of a mixture of two enantiomers. Enantiomers are stereoisomers that are mirror images of each other and cannot be superimposed. A 94% enantiomeric excess means that the mixture contains 94% of one enantiomer and 6% of the other enantiomer.

Let's examine the given answer choices and determine which one accurately describes a 94% enantiomeric excess: A. The product contains 94% of one enantiomer and 6% of the other enantiomer This answer choice is correct, as it accurately describes a 94% enantiomeric excess. B. The product contains 94% of one enantiomer and 6% of other products This answer choice is incorrect because it implies that the 6% contains other products, not the other enantiomer. C. The product contains an enantiomer which is 94% pure. This answer choice is incorrect because it implies that the 94% refers to the purity of a single enantiomer, not the mixture. D. The product contains 97% of one enantiomer and 3% of the other enantiomer This answer choice is incorrect because it describes a different enantiomeric excess (97% vs. 94%).
