Two elements A (Atomic mass = 75) and B(...

Two elements A (Atomic mass = 75) and B(Atomic mass =16) combine to give a compound having 75.8% A. Calculate the relative number of atoms present in B.

Text Solution

Verified by Experts

We are given that Atomic mass of A= 75g
Atomic mass of B= 16g
Also percentage ofA= 75.8%
`therefore` % of B= `100-75.8 = 24.2%`
Relative number of atoms of B with respect of A `= ("% age composition of B")/("atomic mass") = (24.2)/(16)= ~= 1.5`
`therefore` Relative number of atoms in B= 1.5
