प्रश्न
Which of the following would weigh most?
पर्याय
1 mole of H2O
1 mole of CO2
1 mole of NH3
1 mole of CO

उत्तर
1 mole of CO2
Explanation:
Molecular mass of H2O = (1 x 2) + 16 = 18 g
Molecular mass of CO2 = 12 + (2 x 16) = 44 g
Molecular mass of NH3 = 14 + (3 x 1) = 17 g
Molecular mass of CO = 12 + 16 = 28 g
∴ 1 mole of CO2 having maximum molecular mass will weigh more.
