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?
inysia [295]
The equation for density is:
density =  \frac{mass}{volume}

To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>\frac{m}{v}, or \frac{mass}{volume}. Cheesy, but it works!<span>
</span>
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}\\&#10;density = \frac{49\:g}{7\:cm^{3}} \\&#10;density = 7\:g/cm^{3}

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