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

a. Which of the following is true about the mass of the solution. Explain.
i. it is much greater than 280.0 g.
ii. it is somewhat greater than 280.0 g
iii. it is exactly 280.0 g
iv. it is somewhat less than 280.0 g
v. it is much less than 280.0 g

b. Which is true about the volume of the solution. Explain.
i. it is much greater than 200.0 mL
ii. it is somewhat greater than 200.0 mL
iii. it is exactly 200.0 mL
iv. it is somewhat less than 200.0 mL
v. it is much less than 200.0 mL

a. is iii. 100 g H2O + 100 g sugar = 280 g total. That's the law of conservation of mass. 100 + 180 = 280.

b. is v. Solid sugar added to the water will dissolve and leave the volume a little more than 100 mL. The only one that fits is v; i.e., a little more than 100 is much less than 200 mL.

In the future you should show what you think the correct answer is and why you chose that answer.

1. iii

2. V because the sugar dissolves.

a. The mass of the solution will be somewhat greater than 280.0 g. When we mix the sugar and water, the molecules of sugar and water intermingle, resulting in a slightly higher total mass. However, it won't be much greater than 280.0 g because the mass of the sugar and water individually does not change significantly when mixed.

b. The volume of the solution is exactly 200.0 mL. When we pour the 100 mL of sugar and 100 mL of water into a bigger beaker, the total volume remains the same. The particles of the sugar dissolve and spread evenly throughout the water, but the overall volume does not change. Therefore, the volume of the solution is not greater or lesser than 200.0 mL, it remains exactly 200.0 mL.

a. The mass of the solution can be found by adding the mass of the sugar and the mass of the water. In this case, the mass of the sugar is 180.0 g and the mass of the water is 100.0 g. When we pour the two together and stir until the sugar is completely dissolved, the mass of the solution will be the sum of these two masses.

Solution mass = mass of sugar + mass of water
Solution mass = 180.0 g + 100.0 g
Solution mass = 280.0 g

Therefore, the correct answer is iii. The mass of the solution is exactly 280.0 g.

b. The volume of the solution can be estimated by adding the volumes of the sugar solution and the water solution. In this case, both the sugar and water solutions occupy 100 mL each. When we pour the two together, the total volume will be the sum of these two volumes.

Solution volume = volume of sugar solution + volume of water solution
Solution volume = 100 mL + 100 mL
Solution volume = 200 mL

Therefore, the correct answer is iii. The volume of the solution is exactly 200.0 mL.

it is somewhat greater than 280.0g

a) iii.

b) ii.
