Two oxides of a metal contain 25.8% and ...

Two oxides of a metal contain 25.8% and 41.02% of oxygen by weight, respectively. Find the ratio of weights of metal combining with fixed weight of oxygen?

Text Solution

Verified by Experts

Assume the weight of each oxide is 100g.

25.8 g of oxygen reacts with 74.2 g of metal.
1 g of oxygen reacts with `=(1xx74.2)/(25.8)`
= 1.437 g of metal
`:.` The ratio of weight of the metal combining with fixed weight of oxygen in the two oxides is `2.87:1.437=2:1`(apprpx)
