Converting Moles to Grams/Liters/Molecules/Atoms…
Do Now: Convert the following
What is the conversion factor for a) feet to inches: 1 foot = ___inchesb) Feet to yards: 1 foot = ___yardsc) 12 ft = ___________ inchesd) 72 inches = ________ yards
Atomic Mass Units are too small to measure on a laboratory balance, but grams are not. Thus, we use
gram formula mass (formula mass) when converting between
atoms/molecules, moles and grams

Converting moles to grams (or grams to moles)HINT: when finding mass(grams) you have to
calculate formula mass firstConversion factor is…1 mol = formula mass
the set up is…
Given goes here (don’t forget Unit)
The unit you want to convert to goes here
Conversion factor goes here (this unit must be the same as the unit in your given number)
Now we can do # 3 and # 4 together
Nothing goes here
Converting moles to liters (or liters to moles)Conversion factor is…
