Hugh dissolved 2 grams of sugar in 500 grams of water. What was the mass of the solution formed?

Based on the law of conservation of mass, mass is neither created nor destroyed.

In the given, sugar is mixed with water, and since there is no loss from any type, therefore, the total final mass will be equivalent to the summation of the mass of water and the mass of sugar.

Based on the above:

mass of solution = mass of water + mass of sugar

mass of solution = 500 + 2 = 502 grams

We have 500 grams of water from one side and 2 grams of sugar, once added both the total mas will be: total mass = mass of water + mass of sugar = 500 + 2 = 502 grams
