Avery, Anika, and Aiden are conducting an experiment in their physics class. They have a solid object and they want to calculate its density. They have its mass and volume. What formula should they use to calculate the density?

• Density = Mass x Volume

• Density = Mass/Volume

• Density = Mass - Volume

• Density = Volume/Mass

David, Ava, and Charlotte are conducting a science experiment. They need to know the density of water for their calculations. Can you help them? (you should know this, you don't need to calculate)

• 0.5 grams per cubic centimeter

  (0.5 g/cm3)

• 3 grams per cubic centimeter

  (3g/cm3)

• 1 gram per cubic centimeter

  (1 g/cm3)

Elijah, Scarlett, and Kai are working on a science project about different materials. They are particularly interested in gold. Can you help them figure out the density of gold? (no calculation involved)

• 19.3 g/cm³

• 1.3 g/cm³

The ability of salt to dissolve in water is

• Solubility

• Reactivity

• Flammability

• Ductility
