A 0.24 g of coumpound of oxgen and boron was found by analysis to contain 0.096 g of born and 0.144g of oxygen. Calculate the percentage composition of the compound by weight.

Text Solution

Verified by Experts

Mass of the given compound = 0.24 g
Mass of bron = 0.096 g
Mass of oxygen = 0.144 g
`therefore%` age of boron in the given sample
= `0.096/0.24xx100=40%`
% age of oxygen in the given compound
`0.144/0.24xx100=60%`
