Question

It is found that 16.5 g of metal combines with oxygen to form 35.60 g of metal oxide. Calculate the percentage of metal and oxygen in the compound.

Answer 1

35.6 g metal oxide contains 16.5 g metal and 19.1 g oxygen

% metal =$\frac{16.5}{35.6}\times 100$ =46.3%

% oxygen =$\frac{19.1}{35.6}\times 100$ = 53.7%
