x g of element P (atomic weight 15) contains y atoms. How many atoms are contained in 2x g of element Q (atomic weight 30)?

A

2y

B

4y

C

`1/2` y

D

y

Text Solution

Verified by Experts

The correct Answer is:
D
Number of moles of `P = (x)/(15 )` is
Number of moles of `Q =(2x)/( 30 ) = (x)/(15 )`
Equal moles contains equal number of atoms.
