Moles and Molar Mass

Moles = n - Lots of molecules in a chemical is considered in moles

Atomic Mass: Mass of one mole = Molar mass

1 mole = molar mass via grams (depends on the substance)

Dimensional Analysis Steps:

  1. Figure out your converstion factor needed to convert into certain units. For example if you’re converting to moles figure out how many grams you need in your final answer. You can figure this out by figuring out the molar mass of your particular substance which will give you the grams for your conversion

Eg. Moles to mass and vise versa (how many moles is in one gram and vise versa)t

  1. Whatever units you want to cancel out units you put in the numerator in one side and the denominator on the other side

Eg. If you’re trying to find the moles use the converstion factor given to you and eliminate the grams you found in the denominator
