1.	A compound made up of two elements A and B has A=70%, B=30%. Their relative number of moles in the compound are 1.25 and 1.88. Calculate (a) Atomic masses of the elements A and B (b) Molecular formula of the compound, if its molecular mass if found to be 160
Answer» Solution : (a) `"ATOMIC mass of A"=(70)/(1.25)=56` `"Atomic mass of B"=(30)/(1.88)=16` (b) MOLECULAR mass of the compound = 160 Molecular formula of the compound `=Fe_(2)O_(3)`
