Unique End-of-Lab Problems
Chem21Labs has the ability to create unique post-lab problems in the following ways . . . .
- Student Numbers (lab data and calculations) stored in the database - any number shown on a student's webpage can be used in a post-lab problem. Use your creativity to challenge students in ways not possible in the paper environment.
You reported a value of 0.0811 L-atm/mole-K for R using the pressureCO2, volumeCO2, temperatureCO2 and massNaHCO3 collected in lab . . . . what mass of NaHCO3 would you need to start with for your experimental R to be 0.08205 L-atm/mole-K if the water vapor pressure was 25.1 torr (assume all the other parameters are the same as reported in your data section)?
