Answer:

molecules=no. of moles x avagadro no.

here avagadro no. is constant thus higher tge value of moles higher no. of molecules

moles= given mass / molecular mass

1) moles=1/28

2)moles=1/44

3)moles=1/2

4)moles=1/16

we can clearly see that highest no. of moles are there in hydrogen thus highest no. of molecules are there in hydrogen

Thus your answer is 3) 1g of H2
