Molar/molecular mass? methanol's chemical formula is: CH3OH . Mass of C = 12, Mass of O = 16, Mass of H = 1 So, molar mass of methanol is just a sum of masses of elements I listed above. Mass of methanol = 12+3x1+16+1=32 (grams/mole or units)
Methanol= CH3OH C has an atomic mass of 12.011 H has an atomic mass of 1.007 O has an atomic mass of 16 Multiply 1.007 x 4 = 4.028 Add 4.028 + 12.011 + 16 = 32.04 amu is your answer.
