Calculations
: This formula is for calculating the mass of the water

: In order to use this formula to fin the exact volume delivered by the pipet we mustfisrt look at the graph in Figure 1 to find the density of water at the appropiate temp

: we use this formula to take the average volume.

: this formula is to determine the deviation of each...
