Expert Answer

Step 1

mole fraction of a solute in solution is equal to moles of solute divided by the total moles of all component present in solution

Step 2

moles = mass of solute (g)/molar mass (g/mol)

Given here,

mass of helium gas = 2.00 g

molar mass of helium = 4 g/mol

mass of oxygen = 5.46 g

molar mass of oxygen = 16 g/mol

So,

moles of helium gas = 2.00 g/4 g/mol = 0.500...
