Question

What is the Number of atoms in 222 gms of dinitrogen ( N2 ) ???​

Answer 1

Answer:

No. of moles = Molecular weight (M)

Weight (W)

Therefore

(a) No. of moles = 7/28 = 0.25 moles

(b) No. of moles = 2/2 = 1 mole

(c) No. of moles = 16/46 = 0.347 moles

(d) No. of moles = 16/32 = 0.5 moles

Since H2 has maximum no. of moles, hence it has maximum no. of molecules.
