CHEMISTRY FORMULAS

 

Density                                     D = g/L                        mass over volume

 

 

Percent composition     Total mass of element      x       100      =          percent of element

                                    Total mass of compound

 

 

Molarity                       M = moles/L    moles of solute over Liters of solution

 

 

Molality                        m = moles of solute

                                           Kg of Solvent

 

 

Normality                     N = equivalent solute 

                                           Liters of Solution

 

 

Celsius                         Tc = Tk – 273.15

 

 

Kelvin                          Tk = Tc + 273.15

 

 


Fahrenheit                    TF =  TC *  9    + 32

                                                     5

 

Celsius                         TC =  5 (TF – 32)

                                             9

 

TF  + 40 = 9° F

TC + 40    5° C
Misc Info

 

Volume = m3

 

A cubic decimeter (dm3) is often called a liter (L)

dm3 = L

 

The terms weight and mass can be used interchangeably.
