This is about determining the exact concentration of HCl
This is about determining the exact concentration of HCl. Based on the information below, what can you conclude about this lab? What is the deviation?
Results:
| THAM molar mass: 121.1 g/mol | Sample 1 | Sample 2 | Sample 3 |
| Weight of THAM | .8157 g | .8121 g | .8136 g |
| Final buret (ml) | 20.5 ml | 20.6 ml | 44.5 ml |
| Initial buret (ml) | 0.0 ml | 0.0 ml | 23.9 ml |
| Total Volume of HCl (ml) | 20.5 ml | 20.6 ml | 20.6 ml |
| Total Volume of HCl (L) | .02050 L | .02060 L | .02060 L |
| HCl Molarity (Calculated) | .3285 M | .3254 M | .3260 M |
Calculations
HCI Molarity:
Trial 1#: .3285 M Trial #2: .3254 M Trial #3: .3260 M
Best Average Value: .3266 M
% Deviation: ?
M1V1=M2V2
V1=.3 M ×500 ml/ 12 M=12.5 ml HCl
