Question

2.0 g of a metal burnt in oxygen gave
3.2 g of its oxide. 1.42 g of the same
metal heated in steam gave 2.27 of its
oxide. Which law is verified by these
data ?
​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Mass of oxygen in metal oxide= 3.2 - 2 = 1.2 g

Mass of oxygen in second case = 2.27 - 1.42 = 0.85 g

As, 0.85 g oxygen combines with 1.42 g of metal,

1.2 g of oxygen will combine with,

$\frac{1.42 \times 1.2}{0.85} = 2.0 \: g \: of \: metal$

This observation represents a law of definite proportion.
