A sugar syrup of weight `214.2 g` contains `34.2 g` of sugar `(C_(12) H_(22) O_(11))`. Calculate
a. the molal concentration.
b. the mole fraction of the sugar in the syrup.

A

0.55

B

5.5

C

55

D

0.1.

Text Solution

Verified by Experts

The correct Answer is:
A
Water present = 214.2-342=180g
Sugar =34.2 g
`m=(W_(2) xx 1000)/(M_(2) xx W_(1)(g))=(34.2 xx 1000)/(342 xx 180)=0.55`
