Question

Each water sample collected from different source contains
11.11% hydrogen. This data supports
Law of conservation of mass
Law of definite proportions
Law of multiple proportions
Avogadro's law​

Answer 1

Answer:

This data support law of definite portion

Answer 2

Answer:

Correct option is

B law of constant composition

According to the law of constant composition in a given compound, the elements always combine in the same proportion as each other.

Water (H₂O) molecule consists of two hydrogen atoms of relative mass 1 and one oxygen atom of relative mass 16.

Therefore, the ratio in which 2 atoms of hydrogen and one atom of oxygen are combined is 1 : 8 and will always be the same irrespective of the source of water.

Therefore, the correct option is B
