MOLES AND GASES

MOLES AND GASES. Molar Volume. 1 mole of any gas at (STP) standard temperature ( 0  C ) a nd pressure (1 atm ) has a volume of 22.4 cubic decimeters (dm 3 ), which is the same as 22.4 liters (L). This volume of gas is called a molar volume because it is the volume

  1. MOLES AND GASES

  2. Molar Volume 1 mole of any gas at (STP) standard temperature (0C)andpressure (1 atm) has a volume of 22.4 cubic decimeters (dm3), which is the same as 22.4 liters (L). This volume of gas is called a molar volume because it is the volume of 1 mole of a gas at standard conditions.

  3. Moles Volume (L) To calculate molar volume of a gas: (X) Moles22.4 L/mol = Molar volume (L) 1 mol

  4. Volume (L)  Moles To calculate moles: (÷) Molar volume of gas 1 mol = Moles 22.4 L/mol

  5. Sample A: VOLUME (L)  MOLES (÷) A room with a volume of 4000 L contains how many moles of air at STP?

  6. Sample B: MOLES  VOLUME (L) (X) A chemical reaction produces 0.82 moles of oxygen gas. What volume will that gas occupy at STP?

  7. PRACTICE PROBLEMS 1.) A container with a volume of 893 L contains how many moles of air at STP? (L  mol)

  8. 2.) A chemical reaction produces 0.37 mol of N2gas. What volume will that gas occupy at STP? (mol  L)

  9. Convert grams  liters(g  mol  L) 6. 5.0g of H2

  10. 7. 100g of O2
