Question

Did a density lab, is it bad that I have an 11.1% error?

Answer 1

over or under?

Answer 2

over

Answer 3

how did you measure density

Answer 4

With a ruler and triple beam balance

Answer 5

how many measurements did you take and to what uncertainty

Answer 6

3 trials to the hundereths

Answer 7

oh, +-.1 for volume, +/-.01 for mass

Answer 8

what was the substance that you were measurement what at were you comparing it to?

Answer 9

if your volume was of unit order, i.e, ~1
then your error comes almost entirely from your volume error

Answer 10

oh, so I just messed up on the volume some how and did good on the mass?

Answer 11

well if you cannot measure your volume within 10% error, then an 11.1% eroor in your final measurement is fine

Answer 12

error*

Answer 13

Gotcha, thanks so much

Answer 14

(there might be a simple way to reduce your error in volume measurement ; if you are measuring a unit cube, you could measure the length of 3 and then divide by three
