The mole fraction of the 2.2 molal solution whose solvent is naphthalene is 0.28.
Using the relation;
molality = mole fraction × 1000/MA
Where MA = molar mass of the solvent
We know from the question that the molaity of the solution is 2.2 molal
Making the mole fraction the subject of the formula;
mole fraction = molality × MA/1000
MA = 128 g/mol
mole fraction = 2.2 × 128/1000
Mole fraction = 0.28

Answer:
76.86g
Explanation:
the molar mass of sulfur trioxide is about 80.06, so 80.06 grams per mol, 0.96*80.06=76.86g
