What is the percentage error of a 50ml burette, a 10ml volumetric and a 1ml, 5ml and 10ml pipette?
Also what is the percentage error normally for a colorimeter and also the error for a cuvette?

To calculate percentage error you need:
(Error x 100)/Actual Reading
The error is the plus of minus value for a piece of equipment. The burette will typically be plus or minus 1ml. The glassware will depend on the grade of it.
So for your burette, multiply the 0.1ml by 100 and then divide that by the reading you are suing for your titre. Remember though, you are taking two readings from the burette, one from the beginning of the titration and one at the end which means that there are 2 places where your value could be plus or minus that 0.1ml.
Don't quote me on the 0.1ml error though, you need to find out what it is for your equipment.
