Two gaseous sample were analysed. One contained 1.2 g of carbon and 3.2 g of oxygen. The other contained `27.3%` carbon and `72.7%` oxygen. The experimental data are in accordance with

Options

A. law of conservation of mass
B. law of definite proportions
C. law of reciprocal proportions
D. law of multiple proportions.

Answer

B

Explanation

Percentage of carbon in sample 1
`=1.2/(1.2 + 3.2) xx 100 = 27.3 %`
Percentage of oxygen in sample 1 `=3.2/(1.2 + 3.2) xx 100 = 72.7 %`
The two samples have same percentage composition which is in accordance with the law of definite proportions.
