How can you solve for a derived unit involving density?

Question

I don't know what you mean. Density is a derived unit, no mater what the units used are. Do you have an example of what you are doing?

Yes. What is the mass of a sample of material that has a volume of 55.1 cm^3 and a density of 6.72 g/cm^3? D= m/v. I thought that it may be derived unit because of the grams.

If you draw out a factor label table, it may help.

Answer 1

Mass/velocity=kilogram/distance=kg/d/time=kg*t/d=kgt/d=kgs/m
