A (40 % ) by mass sucrose solution is heated till, it becomes (50 % ) by mass. Calculate the mass of water lost from (100 ~g ) of the solution is
Options
- A(10 ~g )
- B(15 ~g )
- C(20 ~g )
- D(25 ~g )
Correct answer
C. (20 ~g )
Step-by-step solution
(40 % ) sucrose solution means it contains (60 % ) water. After heating, till (50 % ) by mass sucrose remains. Thus, ( % ) water lost (= 0.4 0.5 100=80 ) Water lost (=100-80=20 ~g ) Hence, statement (c) is correct.
