1.0 g of H ₂ has same number of molecules as in:

Step-by-step solution

Number of moles of H ₂= 1 2 =0.5 Number of molecules of H ₂=0.5 ~N _ A . (1) Number of moles of N ₂= 14 28 =0.5 Number of molecules of N ₂=0.5 ~N _ A (2) Number of moles of H ₂ O = 18 18 =1 Number of molecules of H ₂ O =1 N _ A = N _ A (3) Number of moles of CO = 16 28 = 4 7 Number of molecules of CO = 4 7 ~N _ A (4) Number of moles of N ₂= 28 28 =1 Number of molecules of N ₂=1 N _ A = N _ A
