1 mole = molar mass (could be atomic mass from periodic table or molecular mass) 1 mole = 22.4 L of a gas at STP ( You do not need to worry about this yet ) Each definition can be written as a set of two conversion factors.
Directions: Complete the following table by using your knowledge of mole conversions. You must show all work on a separate sheet of paper! Mass. (grams) Moles. Atoms/molecules/ ions/particles.
Below the chart, perform the appropriate conversions to get the actual number of moles and atoms/molecules for each sample. Insert your answers into the table (and don’t forget to circle atom or molecule). YOU MUST SHOW ALL WORK WITH UNITS IN ORDER TO GET CREDIT FOR THIS ACTIVITY! 0.5 liter of H2O. Two aluminum cans.
You can calculate the molar mass of a molecule by summing the molar masses of the composing atoms with the help of the periodic table. Use this grams to moles calculator whenever you want to know the number of moles of a substance with a specific mass.
The Mole Map is a powerful tool to visualize mole conversions. If you are struggling, it will quickly help you understand how to convert from moles, to grams, liters, molecules, and back.
Unit 7 Stoichiometry Mole Conversion Worksheet. Name:______________________________. There are three mole equalities. They are: 1 mol = 6.02 x 1023 particles. 1 mol = molar mass in g (periodic table) 1 mol = 22.4 L for a gas at STP. Each equality can be written as a set of two conversion factors. They are:
To convert the grams to moles, we need to know the molar mass of the substance. Remember, molar mass ( M ) is the mass of one mole of atoms/molecules/ions expressed in g/mol. To calculate it we are always going to need a periodic table.
