so my errors are balance (0.01g)
graduated cylinder (0.75 ml)
for the balance i know that i have to do this:
mass of zinc: (3.00/0.01) * 100
mass of copper (2.00/0.01)* 100
and for the total i add that
i am not sure about the graduated cylinder:
i measure a solution 5 times for 5 trials. 1 time for each trial
should i do (50 ml/ 0.75*5) * 100
or just add 0.75 to the total uncertainty and thats it?
Same thing for the voltmeter error, where i do five trials?
thank you in advance
