Hi I am trying to figure out my lab report, I have included the background and the trial information.

Using a 50mL burette, measure out exactly 10.0mL of distilled water and finds its mass. Repeat procedure four times and calculate the error. Assume that the density of water is 1g/mL.

Trial #	Mass of Water (g)	Amount of water dispensed (mL)
1	9.855	9.96
2	9.976	10.02
3	10.008	10.02
4	9.925	10.00
5	9.973	9.99
