Expert Answer:

Molar mass of urea=60 g/mol
Molar mass of C6H12O6 =180 g/mol
R e l a t i v e space l o w e r i n g space i n space v a p o u r space p r e s s u r e equals space N u m b e r space o f space m o l e s cross times fraction numerator M o l a r space m a s s space o f space s o l v e n t over denominator M a s s space o f space W a t e r end fraction
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 0.33 cross times 18 over 50
W over 180 cross times 18 over 100 equals 1 over 60 cross times 18 over 50
W equals 6 space g
