Answer the following questions. SHOW YOUR WORK. I have included the
answers so you can check your work, but I have not included HOW I got those
answers.
1) How many moles are in 22 grams of argon?
There are three definitions (equalities) of mole. They are:
1 mole = 6.02 x 1023 particles
1 mole = molar mass (could be atomic mass from periodic table
or molecular mass)
2)
Each definition can be written as a set of two conversion factors. They are:
