question

A student dissolves 20 g of table salt in a glass of water. Which statement explains what happens to the weight of the table salt after it dissolves?

choices

  • The weight decreases because the pieces of table salt are much smaller.
  • The weight increases because the table salt is spread throughout the water.
  • The weight stays the same because the amount of table salt does not change.
  • The weight is zero because the table salt has become a liquid.
