Moles

A Mol (plural: Moles) is a unit used by chemists to measure atoms. Same principle behind a dozen=12.

1 MOl = 6.02e23 (6.02x10^23). Known as Avogrado’s constant. i call it the avacado number for easy memory

The image above shows a conversion sheet.An example :

To convert an amount of particles to a Mol, multiply like so:

  1. Find amount of particles. For this example, we’ll use 1.25e23.
  2. Multiply it by the equation next to the arrow that points it to the right end item,. in this case Moles. 1.25e23 x 1.00/6.02e23
  3. Solve. = .208

   Those 3 steps work for almost all applications

Molar Mass is the mass of either the element or the compound. For example, the Molar mass of hydrogen is 1.01, which is on the periodic table. For compounds, you add the mass of each individual element. FOr example, H20, you measure 2 Hydrogens and 1 Oxygen. 1+1+16.
