1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP

Mass – Mole Problem:

Convert 6.28 g NaCl to moles

1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP

How many grams of SO2 are in 5.50 moles SO2?

1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP

Particle – Mole Problems

How many atoms are in .920 moles of aluminum?

1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP

How many moles are in 7.82x1024 formula units of CaCO3?

1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP

Mass – Particle

How many molecules are in 6.5 g of NH3?

1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP

If you burned 4.24x1024 molecules of CH4 (methane), what mass of methane did you burn?

1 mole = 6.02x1023atoms, = molar mass (g) = 22.4 L molecules, of any gas Formula units at STP
