A camper burning a piece of paper to start a campfire is a chemical change - the way you can think of this is to consider the fact that the paper cannot be put back together and has become ash, so this is therefore a chemical change. The carbon in the paper is oxidized into other chemical including carbon dioxide. Mass was conserved during this reaction because the mass is still the same, just in a different form.

If the mass of a material is 40 grams and the volume of the material is 9 cm^3, what would the density of the material be?

solniwko [45]

Mass = m = 40 grams
Volume = V = 9 cm³
Density = d = ?

Density is defined as the ratio of mass and volume.

So,

d = m/V

Using the values, we get

d = 40/9 = 4.44 g/cm³

This means the density of material would be 4.44 g/cm³
