What is the volume of 220 grams of an object with a density of 55g/cm square

Chemistry
1 answer:
AnnyKZ [126]3 years ago
4 0
I'm assuming that you meant 55 g/cm^3. Density=\frac{Mass}{Volume}. This is the definition of density. If you rearrange this equation by multiplying each side of the equation by the volume, you get: (Density)(Volume)=Mass. Divide each side by the density to get: Volume=Mass/Density. Now just plug everything in:
V=220 (grams)/55 (grams/cm^3)=<u>4 cm^3</u>
