A) 0.018
B) 0.036
C) 0.0018
D) 0.0036
Correct Answer: D
Solution :
Number of moles of sugar\[=\frac{68}{342}=0.1988\] (\[\because \]Molecular weight of sugar = 342) Number of moles of water\[=\frac{1000}{18}\] = 55.55 [\[\because \] Molecular weight of water =18) \[\therefore \] Mole fraction of sugar \[=\frac{0.1988}{0.1988+55.55}\] \[=0.00356\approx 0.0036\]You need to login to perform this action.
