2. How can you use mass and volume to find density of a
substance?

We use the formula  δ (density)=m/v

Explanation:

The density (δ) is the ratio between the mass and the volume of a compound:

An example:

mass= 120 g ; volume= 15 cm3

δ=m/v= 120 g/15 cm3= 8 g/cm3

it should be all of them because it asks if you included all of those in your answer

explanation:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
