Question
The vapour density of CH3OH is ______. (At. Wt. C = 12, H = 1, O = 16)
Options
32
18
16
34
Solution
The vapour density of CH3OH is 16. (At. Wt. C = 12, H = 1, O = 16)
Explanation:
Molecular weight = Vapour Density × 2
Molecular weight of CH3OH = 12 + 3 + 16 + 1 = 32
V.D. = `(M.W.)/2 = 32/2` = 16
