a compound of X and Y has equal mass of them if their atomic weights a

1.	a compound of X and Y has equal mass of them if their atomic weights are 30 and 20 respectively molecular formula of that compound (its mol.wt.is 120) could be
Answer» Answer: since compound has equal WEIGHTS of X and Y so, Let the WEIGHT be a, So according to question molar mass of the compound is given as 120g so, a+a=120 2a=120 a=60g So, MOLES of X in the compound = 60/30= 2moles and of Y = 60/20= 3moles. So, the REQUIRED FORMULA will be X2Y3. Explanation:

Answer»

Answer: since compound has equal WEIGHTS of X and Y so,

Let the WEIGHT be a,

So according to question molar mass of the compound is given as 120g so,

a+a=120

2a=120

a=60g

So, MOLES of X in the compound = 60/30= 2moles and of Y = 60/20= 3moles. So, the REQUIRED FORMULA will be X2Y3.
