Question

a compound made of 2 elements A and B are found to contain 25%A(At. mass 12.5) and 75%B(at mass 37.5).The simplest formulae of the compound is

Answer 1

ratio of atoms of A is 25/2 is 2
ratio of atoms of B is 75/37.5 is 2
therefore the simplest formula is A2B2

Answer 2

Answer:

AB

Explanation:

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
