20g of sugar is stirred into a beaker containing 100 g of water. after the sugar has completely dissolved, the solution is put on the scale. what is the mass of the solution ? a) 20g b) 80g c) 100g d) 120g

The correct answer is: Option (D) 120g

Explanation:

We are given the following:

Mass of sugar = 20 g

Mass of water = 100 g

When sugar is completely dissolved into water, the mass of the solution will get:

mass-of-solution = mass-of-sugar + mass-of-water

mass-of-solution = 20 + 100

mass-of-solution = 120 g (Option D)
