Uncertainty Calculations

NaCl Uncertainty calculations: For each experiment uncertainty = -0.005

Temperature	Uncertainty Calculation
25	35.63g  +- 0.005  (0.005/35.63)*100 = 0.014%
25	35.31g + - 0.005 (0.005/35.31)*100 = 0.014%
25	34.22g +- 0.005 (0.005/34.22)*100 = 0.015%
40	36.04g + - 0.005 (0.005/36.14)*100 = 0.014%
40	39.11 +- 0.005 (0.005/39.11)*100 = 0.013%
48	33.15 + - 0.005 (0.005/33.15)*100 = 0.015%
50	34.72 + - 0.005 (0.005/34.72)*100 = 0.014%
60	37.80 + - 0.005 (0.005/37.80)*100 = 0.013%
60	About 41g + - 0.5 (0.5/41)*100 = 1.22%

Experiment	Temperature	Uncertainly Calculation
1	26	91.00 %  +- 0.01  (0.01/91.00)*100 =	0.0103%
2	26	78.32% +- 0.01  (0.01/78.32)*100 =	0.0128%
3	39	87.89% +- 0.01  (0.01/87.89)*100 =	0.0114%
4	40	84.00% +- 0.01  (0.01/84.00)*100 =	0.0119%
5	60	50.90% +- 0.01  (0.01/50.90)*100 =	0.0196%
6	55	84.00% +- 0.01  (0.01/84.00)*100 =	0.0119%

The average uncertainty for the final result is 0.013%

Experiment	Temperature o C	Mass Dissolved	Calculations/Note
1	25	35.63g	10.56+20.067+5
2	25	34.22g
3	40	39.11
4	60	41.00	Heated too long
5*	50	34.72
6*	48	33.15
7	40	36.04g
8	25	35.31g
9	60	37.68

*These results are lower than what was expected from research and differ from the trend.

Results from May 29th

These are my final results for my CO₂  !!

Experiment	Temperature (degrees celcius)	Displacement of the Water (mL)	Volume of CO2 added to the water (mL)	Volume of CO2 diss-olved (mL)	Percentage of CO2   dissolved.
1	26	18.0	200	182.0	91.00 %
2*	26	27.1	125	97.9	78.32%
3	39	21.8	180	158.2	87.89%
4	40	16.0	100	84.0	84.00%
5	60	44.1	100	50.9	50.9%
6	55	21.7	150	128.3	84.0%

The graph of temperature vs Percentage of CO₂  dissolved:

The results are fairly spread out, however, they do generally follow the expected trend. Graphing the average  volume dissolved could make this clearer.

Results for Sodium Chloride:

Experiment	Temperature (degrees celcius)	Displacement of the Water (mL)	Volume of CO2 added to the water (mL)	Volume of CO2 diss-olved (mL)	Percentage of CO2 dissolved.
1	26	18.0	200	182.0	91.00 %
2*	26	27.1	125	97.9	78.32%
3	39	21.8	180	158.2	87.89%
4	40	16.0	100	84.0	84.00%
5	60	44.1	100	50.9	50.9%
6	55	21.7	150	128.3	84.0%

With the exception of the results for 50 degrees, the results seem to be sticking to the trend pretty well.

Tomorrow, I may do a final repeat for 50 degrees but apart from that, I am finished my experimentation. :)
