Answer 1

Explanation:

The pair which is having same number of moles are having same number of moleculesa) 16 g O2 No of moles = Given mass in gMolar mass =1632 = 0.514 g N2No of moles = Given mass in gMolar mass =1428 = 0.5No of molecules = Mole × Avogadro number                           =0.5 × 6.022 × 1023                          = 3.011 × 1023 molecules
