A series of volumetric flasks are being prepared for theanalysis of mercury in the drinking water supply using the methodof standard addition. To prepare the flasks, 10 mL of drinkingwater and a varying amount of standard are added to each flask, andthe flasks are brought to the 25.00mL mark on the volumetricflask.
The concentration of mercury standard used was 20.0microgram/mL.
Please use the data tabulated below to provide the concentrationof mercury in the drinking water, in units of micrograms/mL.
It is recommended to use Excel or similar software.
| mL Mercury Standard Added | Signal |
|---|
| 0.00 | 19.65 |
| 1.00 | 30.35 |
| 2.00 | 40.28 |
| 3.00 | 49.78 |
| 4.00 | 60.44 |
| 5.00 | 70.0 |
