Question

4.8 gm of element A ( atomic wt 48) was combined with 3.2 gm of element B ( atomic wt 16) to form an important industrial pigment. what is the formula of the compound ?​

Answer 1

Answer:

x2y3

Explanation:

Let total mass of compound be 100g 

So, mass of X become 75.8g 

Mass of Y become 100−75.8 =24.2g

No. of moles of X=7575.8≃1

No.of moles of Y =1624.2≃1.5

Molecular formula of the compound is 

2×(X1Y1.5) or X2Y3
