An unknown material has a mass of 6.75g and a volume of 9 cm3. what is the density of the material? round to the nearest tenth?

Answer is: the density of the material is 0.8 g/cm³.

m(material) = 6.75 g; mass of unknown material.

V(material) = 9 cm³; volume of unknown material.

d(material) = m(material) ÷ V(material).

d(material) = 6.75 g ÷ 9 cm³.

d(material) = 0.75 g/cm³; density of unknown material.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

the answer is na (sodium)
