If a liquid has a density of 1,200 g/L, what is its density in cg/mL?
A. 1.2 cg/mL
B. 120 cg/mL
C. 12,000 cg/mL
D. 120,000 cg/mL

Answer 1

Multiply by the conversion factors that cancel the units you have and give you the units you want.

`1200(g)/(L)*(1\,L)/(1000\,mL)*(100\,cg)/(1\,g)=(1200\cdot 100\,cg)/(1000\,mL)\\\\=\bf{120(cg)/(mL)}`

Your best choice is ...

... B. 120 cg/mL
