If the mole fraction of SO2 in H2SO4 is 0.2, what is the ratio of mass

1.	If the mole fraction of SO2 in H2SO4 is 0.2, what is the ratio of mass of sulfur and oxygen in the solution?(a) 0.166(b) 6(c) 1.8(d) 0.555This question was addressed to me in class test.Question is from Mole Fraction and Mass(Weight) Fraction topic in portion Moles, Density & Concentration of Basic Chemical Engineering
Answer» The correct option is (d) 0.555 The best I can EXPLAIN: Let moles of SO2 and H2SO4 be x and y RESPECTIVELY, => x/(x + y) = 0.2, => y/x = 4, => ratio of MASS of sulfur and oxygen in SOLUTION = (x32 + y32)/ (x2(16) + y4(16)) = 0.555.
