Using 20 - 200 l micropipette to aspirate 100 l of water five times

	Cumulative mass of volumes 0.001 (g)	Change in mass0.001 (g)	Percentage error (%)	Percentage change in mass (%)
1	0.103	0.103	3
2	0.196	0.093	7
3	0.295	0.099	1
4	0.392	0.097	3
5	0.494	0.102	2

This is a lab report, from which we are expected to calculate the percentage change in mass (%) and Standard deviation (include the full standard deviation calculation)
