Question

which has maximum molecules 7gm n2, 2gm h2, 16 gm no2, 16 gm o2

Answer 1

No. of moles of 7g N2 = 7/28 =1/4;
No. of moles of 2g H2 = 2/2 = 1;
No. of moles of 16g NO2= 16/46 =8/23= 1/3;
No. of moles of 16g O2= 16/32 = 1/2
Here, 1> 1/2 > 1/3 > 1/4
Since, more the no. of moles more will be the no. of molecules.
Thus 2g H2 has the maximum no. of molecules.
