describe the percent error for your molecular weight of citric acid.

Answer 1

Percent Error Formula:

% Error= (∣Experimental Value − Theoretical Value∣ ÷ Theoretical Value) ×100

Experimental Value: The molecular weight you obtained through your experiment.

Theoretical Value: The accepted molecular weight of citric acid (C₆H₈O₇), which is 192.13 g/mol.

Calculate Percent Error:

1. Determine Experimental Value:
2. Example: Assume you measured the molecular weight to be 188 g/mol.
3. Apply the Formula:
4. % Error=(∣188−192.13∣ ÷192.13)×100
5. Simplify: Percent Error=(0.0215)×100=2.15%

A 2.15% error means that your experimental value was very close to the theoretical value of 192.13 g/mol, showing good accuracy.

If your percent error is higher, it might suggest procedural mistakes, impurities, or calibration errors in your measurements.
