Determine the mass of the water by subtracting the mass of the empty container from the mass of the container filled with water: 108.70 g - 83.93 g.
Calculate the mass of the water delivered by the pipet.
Use the density of water at 28°C to convert the mass of the water to volume. The density of water at 28°C is approximately 0.996 g/mL.
Apply the formula for volume: Volume = Mass / Density.
Calculate the true volume of the water delivered by the pipet using the mass obtained and the density of water at 28°C.
