Question

Multiple choice question
A sugar solution contains 15% sugar by weight. When the solution is heated, 40% sugar is left in the solution
The amount of water which is disapperared is -
(1) 0.0625 g
(4) 6.25 g
(2) 62.5 g
(3) 0.625 g
​

Answer 1

Answer:

correct option is (2) 62.5 g

Explanation:

let the mass of solution = 100 g

mass of sugar = 15 g

mass of water = 100-15 = 85 g

on heating some amount water is disappeared and let the new amount of solition is (X) g, which contain 40% sugar equal to 15 g

X × 40/100 = 15

x = 37.5 g

after heating mass of solution is = 37.5 g

mass of water = mass of solution - mass of water

= 37.5 - 15 = 22.5

amount of water disappeared on heating

= (85 - 22.5) = 62.5 g
