Data Table
.........NaHC O3...CaCO3
1. Mass of micro plate.....2.05g....2.05g
2. Mass of micro plate +salt...3.05g...3.05g
3. Mass of Salt .....1g.....1g
4. Moles of salt.....1/84 mol...1/100 mol
5. Mass of unreacted setup...20.66g....17.9g
6. Mass of reacted setup.....20.58g...17.85g
7. Mass of CO2 lost......08g.....0 5g
8. Moles of CO2 lost.....0018mol...0011 mol
9. Mass of Co2 produced as % of mass of sample 8% 5%
(reacted with vinegar)
Questions:
1. Write balanced equation for each raction.
2. From the stoichiometric relationships in the data table, find the # of moles of CO2 actually produced by each reaction.
3. How did the number of moles of CO2 actually produced by each reaction compare with the number of moles that ideally should be produced?
I don’t get how to do numbers 2 and 3. I believe I did number 2 in 8 on the chart but then what is the ideall number of moles? That’s were I am confused please help
