When you print out the notes on powerpoint 11 x 1048 mole s atoms molar mass the mass of 1 mole (in grams) equal to the numerical value of the average atomic mass the mole a counting unit similar to a dozen, except instead of 12, it's 602 billion trillion. Mole conversions the mole bridge : how to use this mole bridge: 1 you are only allowed to go from left to right 2 moles to mass- multiply by the molar mass 50 moles of he atoms 50 moles x: 400g =200g he atoms: 1 mole: 300 moles of h 2 : 300. We will learn how to calculate the molar mass of a compound by using its chemical formula molar mass is a quantity that is very similar to molecular mass, m. To convert from one to the other of these, use the molar mass ratio of the element to that of the chemical species measured in the example above use \courses\chem 311\notes and handouts of concentrationdoc title: units of concentration.
