Question

An aqueous sugar solution is prepared by dissolving 70 g of sugar to get 2000 g of solution. Determine mass by mass percentage of this sugar solution. Also calculate mass of water used??????

Answer 1

Answer:

70/2000 is mass of water used

Answer 2

Answer:

Mass of solvent {water} + Mass of sugar {solute} = Solution

So,

Solution - Solute = Solvent

2000 -   70 = 1930

Explanation:

1930 is the mass of water.

For,  mass by mass percentage:-

Mass of solute/ Mass of solution

=)  70/2000 x 100

3.5%
