Question

a metal form 2 oxide .the higher oxide contain 80% metal .0.72g of the lower oxide gave 0.8g of higher oxide when oxidized. the ratio of wt of oxygen that combine with fixed weight of matter into oxide will be

Answer 1

In higher oxide,

 Wt of metal = 0.8 x 80/100 = 0.64 g

 Wt. Of oxygen = 0.8 - 0.64 = 0.16 g

 In lower oxide,

 Wt. of metal will remain the same as in higher oxide = 0.64 g but

wt. of oxygen = 0.72 - 0.64 = 0.08 g

The ratio of weight of oxygen which combines with a fixed weight of metal in two oxides is

0.16 : 0.08

2 : 1
