Expert Answer:

Given:
 
Atomic weight of A = 20
 
Atomic weight of B = 40.
 
No. space of space moles space of space straight A space equals straight x over 20

No. space of space atoms space of space straight A space equals space straight x over 20 cross times space NA

No. space of space atoms space of space straight A space equals space straight y

No. space of space moles space of space straight B space equals space fraction numerator 2 straight x over denominator 40 end fraction space

No. space of space moles space of space straight B space equals space straight x over 20

No. space of space atoms space of space straight B space equals straight x over 20 cross times NA
