Question

An element a (atomic mass = 75) and b (atomic mass = 25) combine to form a compound. The compound contains 75% a by mass. The formula of the compound will be

Answer 1

Answer:

Element A= 25%

Element B= 75 %

Atomic mass of A =12.5u

Atomic mass of B =37.5u

For element A ratio =25/12.5=2

For element B =75/37.5=2

Hence the simplest ratio will be 1:1

Hence , the simplest formula of the given compound will be A:B
