Converting Moles to Grams, Liters, Molecules, and Atoms
Converting Moles to
Grams/Liters/Molecules/Atoms…
Do Now: Convert the following
What is the conversion factor for
a)
feet to inches: 1 foot = ___inches
b)
Feet to yards: 1 foot = ___yards
c) 12 ft = ___________ inches
d) 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
