Answer:
Molar mass = 3.9236 g/mol ≅ 4 g/mol
This corresponds to Helium gas.
Explanation:
Let the moles of nitrogen gas = x moles
Moles of carbon dioxide = x moles ( As both are filled at same temperature and pressure conditions )
Given:
Molar mass of nitrogen gas, = 28.014 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of nitrogen gas = 28.014x g
So,
Let,
Similarly,
Molar mass of nitrogen gas, = 44.01 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of nitrogen gas = 44.01x g
So,
Solving the two equations, we get :
x = 0.00943 moles
Thus, Given:
Mass of the gas = 0.037 moles
Moles = 0.00943 moles
The formula for the calculation of moles is shown below:
Thus,
Molar mass = 3.9236 g/mol ≅ 4 g/mol
This corresponds to Helium gas.
