Question

Hugh dissolved 2 grams of sugar in 500 grams of water. What was the mass of the solution formed? I think it's A.

1,000 grams
502 grams
500 grams
498 grams

Answer 1

The answer would be 502 grams because of the law of conservation of mass, you can't create or destroy mass so then 2 grams plus 500 grams is 502. I am 100% positive that B is correct.

Answer 2

The correct answer is the option 502 grams.

The law of conservation of mass says that the mass cannot be created or destroyed. Hence, the 2 grams of the sugars and the 500 grams of the water together as a solution would make a total of 502 grams of the solution. The sugars may not be visible due to dissolving, but the mass of the sugar would still be there in the solution.
