If the equivalent mass of a metal is double that of oxygen then the weight of its oxide is ___ times greater than the weight of the metal.

A

4

B

2

C

3

D

1.5

Text Solution

Verified by Experts

The correct Answer is:
D
Equivalent mass of metal `= 16 = ( x)/( n ) `
where x = atomic mass of metal
n = valency of metal
Molacular formula of metal oxide `= M_(2)O_(n)`
`( "Mass of metal oxide")/( "Mass of metal ") = ( 2( 16n) + 16 ( n ))/(2(16n)) = 1.5 `
