Question

Which has maximam number of molecules?(a)7gm of N2(b)2gm of H2(c)16gm of No2(d)16gm of O2 questen ka answer kaya hoga.

Answer 1

a) Molecular mass of N2 = 14 g
Given Mass = 7 gm
Number of moles = Molecular mass /Given mass
= 14/7 = 2 moles .

b) Molecular mass of H2 = 2g
Given mass = 2 g
Number of moles = Molecular mass/Given mass = 2/2=1 mole

c) Molecular mass of No2 = 46 g
Given Mass = 16 g
Number of moles = Molecular mass /Given mass = 46/16 = 2.875 moles

d) Molecular mass of O2 = 16 g
Given Mass = 16 g
Number of moles = Molecular mass / Given mass = 16/16 = 1 mole .

Part c) No2 , number of moles = 2.875 is having largest number of molecules.
