1 g of H ₂ contains the same number of molecules as in
Options
- A14 g of N ₂
- B18 g of H ₂ O
- C16 g of CO
- D28 g of N ₂
Correct answer
A. 14 g of N ₂
Step-by-step solution
Number of moles of H ₂ = 1 2 = 0.5 mol. Number of moles of N ₂ in 14 g = 14 28 = 0.5 mol. Number of moles of H ₂ O in 18 g = 18 18 = 1 mol. Number of moles of CO in 16 g = 16 28 = 4 7 mol. Number of moles of N ₂ in 28 g = 28 28 = 1 mol. Since the number of moles of 1 g of H ₂ and 14 g of N ₂ are equal, they contain the same number of molecules. Answer: 14 g of N ₂
