How many moles are in 1.2 x 10' grams of ammonia, NH3?
9)
How many grams are in 2.3 x 104 moles of calcium phosphate, Cas(P0,)h?

There are three definitions (equalities) of mole. They are:
1 mole = 6.02 x 102 particles
1 mole = molar mass (could be atomic mass from periodic table or molecular mass)
1 mole = 22.4L 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. They are:
1 mole = molar mass(g) can be written as
1 mole
molar mass (g)
molar mass ()
1 mole
OR
Example:
If we know the relationship between mass and moles for a substance we can easily convert between the two. For example
we know that the mass of one mole of NaCl is 58.44 g (equivalent then is one mole = 58.44g). We can now determine the
number of moles in 100.0 g by the following calculations.
1 mole
100.0 g NaCl
=1.711 moles NaCl
58.44g
Or if we have 5.06 moles and we want to know the mass:
58.44 g
5.06 mbles NaCI
- 296 g NaCI
1 mole
