I have a few things I need some help with.

Does anyone know how many cubic decimeters are in 1 liter?

And would anyone be able to help me with this problem?
The density of a substance is 2.7 g/cm³. What is the density of the substance in kilograms per liter?

Thank you so much! Any help is appreciated!

1 cubic decimeter = 1 liter.

2.7 g/cc = 2.7 kg/liter
