Question

If the mass of a material is 49 grams and the volume of the material is 7 cm^3, what would the density of the material be?

Answer 1

The equation for density is:
$density = \frac{mass}{volume}$

To help you remember - my teacher told us to remember "We ♡ density," and the heart stands for $\frac{m}{v}$, or $\frac{mass}{volume}$. Cheesy, but it works!

Back to the problem:
We know the mass if 49g and the volume is 7 $cm^{3}$, so plug these values into the equation for density:
$density = \frac{mass}{volume}\\ density = \frac{49\:g}{7\:cm^{3}} \\ density = 7\:g/cm^{3}$

Answer: The density is 7 g/$cm^{3}$
