    % error depends on your final result.

    to find the accuracy, take the smallest division and halve it. you should be able to read to 0.5mm on a ruler with 1mm divisions. therefore the error is also 0.5mm, because you could be 0.25mm over or under and still write 0.5mm.

    to do error calculations without help, you need to understand them yourself. we had a horrific question on this once and i did it and got full marks not because of any practice (we did about 10 minutes), but because I understood what I was doing, and knew when to add errors and when to multiply them by constants.

    think about what you're doing and you should get the hang of it.

    Burettes measure to the nearest 0.05 cm^3, giving a 0.1 % error.

    Glass bulb pipettes measure to the nearest 0.05 cm^3, giving 5 %, 2.5 %, 1 % and 0.5 % errors respectively.

    Can't help you with the other two I'm afraid!
