Question

Calculate the molecular masses of the following compounds:
i. Methanol (CH3OH)
ii. Ethanol (C₂H5OH)

PLEASE CALCULATE. I AM MARK BRAINLIST

AND 50 POINTS​

Answer 1

Answer:

The molecular masses of methanol (CH3OH) is 32u and that of ethanol (C2H5OH) is 46u.

Explanation:

In any compound, the sum of atomic masses of all the elements is called the molecular mass

Ch3OH = 1 X C +3 X H + 1 X O + 1 X H = { 12+3+16+1 } u= 32u

C₂H5OH= 2 X C +5 X H + 1 X O + 1 X H ={24+5+16+1} u= 46u

Answer 2

Answer:

(a) Molecular mas of Methanol (CH

3

OH)=1×C+3×H+1×O+1×H=(12+3+16+1)u=32u

(b) Molecular mass of Ethanol (C

2

H

5

OH)=2×C+5×H+1×O+1×H=(24+5+16+1)u=46u
