Volumetric Pipetting

Using 100 - 1000 l micropipette to aspirate 1ml of water until 5 ml is pipetted

Cumulative volumes (ml)	Cumulative mass of volumes (g)	Change in mass (g)	Percentage error (%)	Percentage change in mass (%)
1	0.992	0.992	0.8	0
2	1.995	1.003	0.3	101
3	3.026	1.031	3.1	51.7
4	4.046	1.020	2	33.7
5	5.039	0.993	0.7	24.5

This is a lab report, in which we are asked to calculate the standard deviation result. (including the full standard deviation calculation)
