5)
How many grams are in 4.5 moles of sodium fluoride, NaF?
6)
How many moles are in 68 grams of copper (II) hydroxide, Cu(OH)2?
7)
How
many grams are in 3.3 moles of potassium sulfide, K2S?

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 =22.4 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. They are:
1 mole =molar mass(g) can be written as
1 mole
molar mass (g)
OR
molar mass (g)
1 mole
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 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 moles NaCI
-296 g NaCI
1 mole
Solve the following
1) How many moles are in 15 grams of lithium?

Volumetric pipets are calibrated in a manner that takes into account the solution which remains at the tip. True Using the pipettor, you should turn the wheel on the pipette, draw up the solution until the meniscus is several centimeters above the calibration line, then quickly remove the pipette and put your thumb over the open hole of the pipet.
