It also has the actual error values for equipment. If a number of different people carry out the same measuring procedure and the values are close the procedure is reproducible. Arithmetical procedures can lead to uncertainty...

The circumference of the 2p coin is therefore 81 mm. The system returned: (22) Invalid argument The remote host or network may be down.

For the electronic weighing scale, assuming it reads to 2dp, then the error would be ±0.005. However, the overall calibration can be out by a degree or more. If the same person obtains these close values, then the experimental procedure is repeatable. Your cache administrator is webmaster.

Wrong forum! Please try the request again. If ur using a 2 dp balance, the error is 0.005*2=0.01 g #8 abbie, Apr 22, 2007 hash118118 New Member Joined: Feb 21, 2007 Messages: 237 Likes Received: 0 abbie Sign in Oops, something wasn't right please check the following: Sign in Username Password Forgot password?

But that works best for stuff like mass and length. http://setiweb.org/percentage-error/percentage-error-50-ml-pipette.php Don't say that you foolishly added too much of a chemical or something cos that will lose you implementation marks.

I don't think you understand the concept of percentage errors - you are analysing the errors assosciated with the appartus you have used - these errors are beyond your control.

You want to know the circumference of a 2p coin! if u divide this by the result you get the precentage uncertainty/error. So if it is to 2 decimal places the absolute uncertainy is ± 0.005 units. weblink The system returned: (22) Invalid argument The remote host or network may be down.

This is what i have done I used mostly volumetric equipments. Use your answer to calc the percentage error in the titre volume of 11.30cm³ My answer: ± 0.05cm³ (0.05*2)/11.30 * 100 = 0.88% which was correct If I try it with i dunno about the percentage error thing, she said something about 0.1%, but dunno if that was for the heating method or for the titration.
