To change between moles, mass, and volume, you only need to remember a few important relationships.
Moles to Mass:
Use this formula:
Mass (grams) = Moles × Molar Mass (grams per mole)
If you know how many moles you have and the molar mass of the material, you can easily calculate the mass.
Mass to Moles:
This one is just the opposite:
Moles = Mass (grams) ÷ Molar Mass (grams per mole)
Moles to Volume (for gases):
When conditions are normal (like standard temperature and pressure), one mole of any gas takes up about 22.4 liters. You can use this for your calculation:
Volume (liters) = Moles × 22.4 liters per mole
Understanding these simple conversions will really help you when you're working through chemical reactions!
