A glass bottle with a mass of 0.25kg is 1.5kg when it is full of water. If the bottle is full of alcohol, how much alcohol can it contain? Alcohol = 0.8 × 10 cubic kg / m3

A glass bottle with a mass of 0.25kg is 1.5kg when it is full of water. If the bottle is full of alcohol, how much alcohol can it contain? Alcohol = 0.8 × 10 cubic kg / m3


Mass of water = 1.5-0.25 = 1.25Kg
The density of water is 1kg / L
So bottle volume = water volume = 1.25 △ 1 = 1.25l
The density of alcohol is 0.8kg/l
Alcohol mass = 0.8 × 1.25 = 1kg
