What will be the value of mole fraction of the solute in 1.00 molal aqueous solution?

Question

Vimal Swarnkar · Accepted Answer

(c) 0.0180. 1 molal = 1 mol solute in 1000 g water (1000/18 = 55.5 mol). x(solute) = 1/(1 + 55.5) = 0.0177 ≈ 0.018 → (c). Trick: mole fraction must be < 1, so (a) and (b) are out at once.

Answer

(a) 1.7700

Answer

(b) 1.7770

Answer

(d) 0.0344
