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) =
Volumex (Weight/ Volume)
Or, Volume x Density = Weight
And, Volume x Density / Density = Weight /Density
Density / Density= Weight /Density
Therefore, Volume = Weight / Density
With 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.
