An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K^-1 mol^-1.

1. If the vapor pressure of water had not been taken into account, what would have been the calculated value of R?

2. If the syringe volume had been incorrectly read giving a calculated system volume of 25.6 mL what would have been the percent error in the calculated value of R?

3. 1) what is the volume of one mole of hydrogen gas at 273 K and 760 torr?

2) what is the volume of one mole of oxygen gas under the same conditions?

3) what does this suggest concerning the ideal gas law?

4. Show how boyles and Charles' laws may be derived from the ideal gas law.

5. Two moles of an ideal gas originally at 380 torr and 298 K are compressed at constant temperature to 680 torr. Find the initial and final volumes.
