Question

Quizplus · Accepted Answer

Formula mass of water (H2O) = 2(1.008 amu) + 1(15.999 amu) = 18.015 amu
Formula mass of propene (C3H6) = 3(12.011 amu) + 6(1.008 amu) = 42.080 amu
Formula mass of 2-propanol (C3H8O) = 3(12.011 amu) + 8(1.008 amu) + 1(15.999 amu) = 60.096 amu

Therefore, the correct answer is C) water: 18 amu; propene: 42 amu; 2-propanol: 60 amu.
