Mason and Kai decided to whip up a delicious snack with raspberries, blueberries, walnuts, and a sprinkle of sugar. They popped it in the fridge for an hour. When they returned, the sugar had mysteriously vanished, but the fruit and walnuts looked just the same!

What magical transformation do you think happened to the powdered sugar? 

• The sugar evaporated due to the lower temperature in the refrigerator. 

• The sugar was very dense, so it sank to the bottom of the container

• The sugar dissolved because of the moisture in the fruit. 

• The sugar melted into a liquid state

• The mass of the solution is 92 g.

  
  

• The volume of the solution is 22 mL.
