Question

a loaf of bread has a volume of 700 cm3 and a mass of 420 g. what is the density of the bread?

Answer 1

We know that the equation for density is:

$D=\frac{m}{V}$

where D is the density, m is the mass in g, and V is the volume in either mL or cubic centimeters.

So then, given two of the variables, we can solve for density:

$D=\frac{420g}{700cm^{3}}$

$D=\frac{0.6g}{cm^{3}}$

Therefore, the density of the bread is 0.6g per cubic centimeter.
