Question

To prepare 600 g of a 30%w/w sugar solution, calculate the amounts of
sugar and water needed.

Answer 1

Answer:

Mass percentage of cane sugar = 25

We know that,

Mass percentage=

Mass of solution

Mass of solute

×100

So, 25=

250

Mass of canesugar

×100

or

Mass of canesugar=

100

25×250

=62.5g

Mass of water = (250-62.5)=187.5 g

hope it helps!!

Answer 2

Given - volume and concentration

Find - Amount of water and sugar needed

Solution - The amount and water needed are 180 grams and 420 grams respectively.

The amount of sugar needed can be calculated by the formula -

Mass percentage = mass of solute/mass of solution*100

30 = mass of solute/600*100

Mass of solute = 30*600/100

Mass of solute = 180 grams

Amount of water needed = 600 - 180

Amount of water needed = 420 grams

Hence, the amount of sugar and water needed is 180 grams and 420 grams respectively.
