Question

F. Which of the following has maximum
number of molecules ?
a. 7 g N
b. 2 g H
c. 8 g 02
d. 20 g NO,
2​

Answer 1

Answer:

2gH2

Explanation:

Answer 2

Answer:

b. 2 g H

Explanation:

we know that,

No. of moles is given by

=Molecular weight (M) / Given weight (W)

Therefore,

A) no. of moles in a option = 7/28= 0.25 moles

B) No. of moles in b option i.e H^2= 2/2= 1 moles

C) number of moles in c option = 16/46 = 0.347 = 1 mole

D) No. of moles in D option= 16/32=0.5 moles

Now as H2 has maximum no. of moles, thus it has maximum no. of molecules
