Solubility and Molarity Quiz

What is the definition of solubility as discussed in the video?

• The amount of solute that can dissolve in 1 gram of solvent at a given temperature.

• The maximum mass of solute that can saturate 100 grams of solvent at a given temperature.

• The temperature at which a solute completely dissolves in a solvent.

• The volume of solvent required to dissolve a given mass of solute.

How is solubility calculated according to the formula provided?

• Mass of solute divided by temperature.

• Volume of solvent divided by mass of solute.

• Mass of solute times 100 divided by volume of water used.

• Volume of water used times 100 divided by mass of solute.
