Question

If you mix 100 grams of sugar into a 1,000ml beaker, and the sugar

dissolves so you can no longer see it, how much sugar is in the beaker?

Answer 1

100g

Step-by-step explanation:

The amount of sugar in the beaker still remains 100g. There is no addition or loss of any quantity of sugar unit.

Physical and chemical changes obey and complies with the law of conservation of matter.

The law suggests that matter is neither created nor destroyed but can be changed from one form to another.

• In this process, if we do a reverse reaction by evaporating the solution in the dish, we would get back 100g of sugar.
