$0/1$ pt $100$ Details

While a $25mL$ pipet should theoretically measure out exactly $25\mathrm{.}00mL,$ this is not always the case. A student determined the actual volume of a $25mL$ pipet by measuring the mass of the water delivered by the pipet and then calculating the volume from the known density of water. The density of water is $0\mathrm{.}99820\frac{g}{m}L$ at $20C.$ This measurement was done three times, and the following results were obtained. Calculate the average volume delivered by the pipette and the percent error of the pipet.
