Explanation / Answer

You were doing good there. =) So you have 1.25 L = 1250 mL. Good, and the percentage will convertto .014. So now, multiply 1250 mL by .014. You should get the number of mLin Phenol. So now take the Density and multiply it by the answer you obtain.This will get your answer in grams. Hoped that helped you out. Have a good weekend.
