Q37Long answer
Which has more number of atoms? 100g of N2 or 100 g of NH3
Show answer
(i) 100 g of N2 = moles Number of molecules = × 6.022 ×1023 2 ×100 Number of atoms = × 6.022 ×10 23 = 43.01×1023 100 100 (ii) 100 g of NH3 = moles = × 6.022×1023 molecules 17 17 = × 6.022 ×1023 × 4 atoms = 141.69 ×1023 NH3 would have more atoms SLVS
