Question

An aqueous solution of Methyl alcohol contains 48g of alcohol. The mole
fraction of alcohol is 0.6. The weight of water in it is

Answer 1

Explanation:

Methyl alcohol =CH3OH

$x \: alcohol \: = \frac{n \: alcohol}{n \: alcohol + n \: water}$

$= > 0.6 = \frac{ \frac{48}{32} }{ \frac{48}{32} + \frac{x}{18} }$

$= > \frac{x}{18} = 1$

$= > x = 18gm \:$
