Mass Conservation in Solutions Quiz

What happens to salt when it is added to water and dissolves?

• It disappears.

• It evaporates.

• It remains in the water.

• It turns into gas.

After salt dissolves in water, what happens to its particles?

• They vanish.

• They stay in the water.

• They settle at the bottom.

• They evaporate.

What does the mass of the solution equal to?

• The mass of the solvent.

• The mass of the solute.

• The sum of the masses of the solute and solvent.

• Less than the mass of solute and solvent combined.

What is true for any solution?

• The solute disappears.

• The mass of the solution equals the total mass of solute and solvent.

• The solvent evaporates.

• The solute settles at the bottom.

What formula is given in the text for mass in a solution?

• Mass of solute × mass of solvent = mass of solution.

• Mass of solvent − mass of solute = mass of solution.

• Mass of solute + mass of solvent = mass of solution.

• Mass of solvent × mass of solute = mass of solution.

When salt dissolves in water, has any mass been lost?

• Yes.
