Detailed explanation-1: -Answer: H2O has the smaller molar mass.
Detailed explanation-2: -CONCLUSION. Molar mass can be defined as the smallest unit of mass of any compound and is the twelfth of one carbon mass-12 atoms.
Detailed explanation-3: -Explanation: At a particular temperature, the average kinetic energy of all gaseous molecules is equal. Since hydrogen gas has the lowest mass out of these gases, it will have the highest average velocity.
Detailed explanation-4: -(IV) 1.6 g (0.025 mole) of carbon dioxide contains 0.8 g (0.05 mole) of oxygen. It contains least weight of oxygen.
Detailed explanation-5: -The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.
