Concentration units
Units that support prefixes are shown in bold.
Unit Name, System | Units Students Enter | Infix You Code | Notes |
Henry’s law constant units SI |
mol*(L*atm)^(-1) | mol*(L*atm)^(-1) | |
molal (molality) SI |
m mol*kg^(-1) |
molal mol*kg^(-1) |
You must code concentration as molal so it is not confused with m for meter. Avoid coding in base units. |
molarity SI |
M mol/L mol*m^(-3) |
M mol/L mol*m^(-3) |
Code chemical concentration in M unless you specifically need mol/L. Avoid coding in base units (mol/m^3). |
mole SI |
mol mole moles |
mol | For student input, mol, mole, and moles are considered acceptable alternate spellings, but you should code answers using the infix mol. |
parts per billion SI |
ppb | ppb | |
parts per million SI |
ppm | ppm |
