If the density of a substance is 15.2 g/mL, what is the density in cg/kl?

Answer 1

change ml to cm^3, then to dm^3
change kl to 1000dm^3

15.2g/mL*1ml/cm^3*1000cm^3/dm^3 *1000dm^3/kl

now, take all that in g/kl and change the grams to cg,by multiplying 100cg/g

Answer 2

seems like a lot of work.
mL = 10^-3L
kL = 10^3L = 10^6mL

cg/kL = g/mL * 100cg/g * 10^6mL/kL = g/mL * 10^8
