What is the average weight of deionized water transferred when calibrating a pipet with a fixed delivery of 10.0 µL?

To determine the average weight of deionized water transferred when calibrating a pipet with a fixed delivery of 10.0 µL, it’s important to understand the relationship between volume and mass in the context of water, which has a density of approximately 1 g/mL at room temperature.

Since 1 g = 1000 mg, this means that 1 mL of deionized water weighs 1000 mg. Consequently, if you have a volume of 10.0 µL (which is 0.010 mL), you can calculate the weight in milligrams as follows:

1. Convert 10.0 µL to mL:

10.0 µL = 10.0 x 10^-3 mL = 0.010 mL.

2. Using the density of water (1 g/mL), we calculate the mass:

Mass = Volume x Density = 0.010 mL x 1000 mg/mL = 10.0 mg.

Thus, when a pipet is calibrated to deliver 10.0 µL of deionized water, the average weight of water transferred is accurately represented as 10.0 mg. This reflects
