Question

If we add 40 g sugar to 200 g of 20 % sugar water solution, what would be the new concentration of solution?

Answer 1

Answer:

present amount of solute in sugar is called it's concentration

Answer 2

Answer:

33.33 %

Explanation:

Given:-

40 g of sugar

200 g of sugar water solution containing 20% sugar

Statement:-

The 40 g of sugar is added to the sugar-water solution.

To find:-

Concentration percent of sugar in solution.

Solution:-

Finding grams of sugar added in water before adding more:-

20 % of 200

20/100 * 200

20 * 2

40 g

Quantity of water:-

200 - 40

160 g

Total quantity of sugar to make the solution:-

Sugar in solution + Extra sugar (Given)

40 g + 40 g

80 g

Weight of solution (Making the solution):-

Water + Sugar

160 g + 80 g

240 g

Finding concentration of sugar (Mass percentage):-

(Mass of solute / Mass of solution) * 100

(80 g / 240 g) * 100

800/24

33.33 %

Hence, adding 40 g of sugar to a 200 g sugar water solution with 20 % concentration will result in its increase up-to 33.33 %.
