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.

Option (c) is the correct answer.

Explanation:

According to law of conservation of mass, mass of the materials that are reacting with each other are not affected by a chemical change and it only transforms from one form to another.

Hence, the reaction between sugar and water will follow law of conservation of mass.

      Sugar and water = mass of sugar + mass of water

                                   = 180.0 g + 100.0 g

                                    = 280.0 g

Thus, we can conclude that it is true about the mass of the solution that it is exactly 280.0 g.
