Question:
You are asked to callibrate a 25.00mL volumetric pipet. You determine that the temperature of your distilled water is exactly 24.5 degrees Celsius (which has a density of 0.997171g/mL). You determine the mass of a clean dry beaker and found that it was 58.1884 g. You filled water up to the mark and transferred this to the beaker and found that the new mass was 82.9658 g. What is the actual volume of the pipet?
