Solution

Given that:

The Mass of the sample = 0.24g

Mass of boron in the given sample = 0.096 g

Mass of oxygen in the given sample = 0.144 g

% composition of compound = [% of boron] + [% of oxygen]

Therefore,

%compositionofboron=MassofboronMassofsamplecompound×100

%compositionofboron=0.0960.24×100=40%

Therefore,

%compositionofoxygen=MassofoxygenMassofsamplecompound×100

%compositionofoxygen=0.1440.24×100=60%

The percentage composition of the boron and oxygen in the compound by weight is 40% and 60% respectively.
