Which of the following has maximum number of moles?a)1g of O2b)...
Explanation:
Therefore, 1g of H2 has the maximum number of moles (0.5 moles) compared to the other options.
- The number of moles is directly proportional to the mass of the substance.
- The molecular mass of H2 is 2 g/mol, which means that 1 g of H2 has 0.5 moles (1/2 = 0.5).
- The molecular mass of O2 is 32 g/mol, which means that 1 g of O2 has 0.03125 moles (1/32 = 0.03125).
- The molecular mass of Cl2 is 71 g/mol, which means that 1 g of Cl2 has 0.01408 moles (1/71 = 0.01408).
- The molecular mass of N2 is 28 g/mol, which means that 1 g of N2 has 0.03571 moles (1/28 = 0.03571).
Therefore, 1g of H2 has the maximum number of moles (0.5 moles) compared to the other options.
