Question

What is the simplest formula of a compound containing 50% of element A(atomic mass10) and 50% of element B(atomic mass 20)?

Answer 1

Simplest formula stands for Empirical formula
So, we have percentage compositions and we have to divide them with atomic weight
A=50/10=5
B=50/20=2.5

Divide by minimum value

A=5/2.5=2
B=1
Emp. formula is A2B
