Question

how much water will be recovered on complete evaporation of 500 gm of sugar solution whose concentration is 20%​

Answer 1

Answer:

Initial condition

:− 40% sugar (by mass),

Therefore, In 100gm of an aqueous solution, 40g sugar and 60g water is present.

Final condition

:− 50% sugar (by mass),

Therefore, In 100gm of an aqueous solution, 50g sugar and 50g water is present.

Amount of water to be evaporated =60−50=10 grams
