Answer:
This question is incomplete
Step-by-step explanation:
This question is incomplete. However, in order to calculate the percentage yield of an extraction/isolation, the formula to be used is below
percent yield = isolated mass/total mass × 100
The mass of the yield (which can also be referred to as isolated mass) was provided to be 0.15 g but the total mass of the (4-chlorophenyl)bis(4-methoxyphenyl)methanol was not provided.
In the completed question that has the total mass or the values to obtain the total mass, the formula mentioned earlier should be used.
