Question

2.5 g of sugar is dissolved in 47.5g of water. Calculate its concentration as percent by mass.

Answer 1

Answer:

Sugar = 5 % and water = 95 %

Explanation:

Amount of sugar = 2.5 g

Amount of water = 4.7 g

Sum of the total amount of sugar and water = (2.5 + 4.7) g = 50g

Mass by percent of sugar= 2.5 / 50 ×100 = 5 %

Mass by percent of water = 100 - 5 = 95 %
