A compound made up of two elements A and...

A compound made up of two elements A and B has `A = 70%, B = 30%`. Their relative number of moles in the compound is 1.25 and 1.88, calculate :
Atomic masses of the elements A and B

Text Solution

Verified by Experts

`"Relative no. of moles of an element"=(%" of the element")/("Atomic mass") or "Atomic mass"=(%" of the element")/("Relative no. of moles")`
`therefore" Atomic mass of A"=(70)/(1.25)=56," Atomic mass of B"=(30)/(1.88)=16`
