You have two beakers, one filled to the 100-mL mark with sugar (which has a mass of 180.0g) and the other filled to the 100-mL mark with water (mass of 100.0g). You pour all the sugar and all the water together in a bigger beaker and stir until the sugar is completely dissolved.

Which of the following is true about the mass of the solution? Justify your answer.

a) It is much greater than 280.0g.

b) It is somewhat greater than 280.0g.

c) It is exactly 280.0g.

d) It is somewhat less than 280.0g.

e) It is much less than 280.0g.

I think the correct answer from the choices listed above is option C. The mass of the solution is exactly 280.0 g if the measurement of each of the components before being mixed are precise. This is governed by the law of conservation mass where it states that mass cannot be destroyed or created.
