Abby mixes 2 moles hydrogen with 1 mole oxygen to produce water. She expects to produce 2 moles water, but she captures 1.5 moles water. In this case, the value 1.5 moles represents which type of yield?

Theoretical yield is the maximum amount of product predicted from the balanced equation and the starting amounts: here, Abby expects 2 moles of water. Actual yield is the amount of product she really obtains, which is 1.5 moles. Therefore, 1.5 moles is the actual yield.
