  1. 20. What size container do you need to hole 0.0459 mol of N2 gas at STP? 0.0459 mol *22.4L = 1.03 L • 1 mol

  2. 22. What volume in milliliters will 0.00922g of H2 gas occupy at STP? 0.00922 g 1 mol= 0.00457 mol 2.0 g 0.00457 mol* 22.4 L = 0.102 L 1 mol • or 102 mL

  3. 24. Calculate the volume that 4.5kg of ethylene gas (C2H4) will occupy at STP.

  4. 26. Determine the Celsius temperature of 2.49 mol of a gas contained in a 1.00-L vessel at a pressure of 143 kPa.

  5. 27. Calculate the volume of a 0.323-mol sample of a gas at 265 K and 0.900 atm.

  6. 28. What is the pressure, in atmospheres, of a 0.108-mol sample of helium gas at a temperature of 20.0 oC if its volume is 0.505 L

  7. 29. If the pressure exerted by a gas at 25 oC in a volume of 0.044 L is 3.81 atm how many moles of gas are present?
