Glycerine is a syrupy liquid at room temperature which is used as the base for many medicines. Substances like glycerine are often ordered in units of volume (cc) , but are measured by weight (grams).

Converting these two values is important, and pretty easy!Remember, Density= Weight/Volume

So, Volume x (Density) = Volume x (Weight/Volume)

Volume x (Density) =~~Volume~~x (Weight/~~Volume)~~

Or, Volume x Density = Weight

And, Volume x Density / Density = Weight /Density

Volume x~~Density / Density~~= Weight /Density

Therefore, Volume = Weight / DensityWith a little practice, you can learn to move equations around easily.

If glycerine has a density of 1.25 grams/cc, find the weight in grams for a 45 cc order of glycerine.
