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)

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
