Pure toluene (C7H8) has a normal boiling point of 111.0°C, and the Boiling Point Elevation Constant is 3.40°C. When 25g of compound A (MM=100) is dissolved in 500g of Toluene, the boiling point of the solution is 113.2°C. Therefore, the activity coefficient of the compound (γA) in the solution is approximately: a) 1.3 b) insufficient data c) 0.65 d) 0.8

Question

Pure toluene (C7H8) has a normal boiling point of 111.0°C, and the Boiling Point Elevation Constant is 3.40°C. When 25g of compound A (MM=100) is dissolved in 500g of Toluene, the boiling point of the solution is 113.2°C. Therefore, the activity coefficient of the compound (γA) in the solution is approximately:

a) 1.3

b) insufficient data

c) 0.65

d) 0.8

(The answer according to the professor is 1.3, but I have tried and can't get that answer, thanks for the help)
