Add a comment Submit · just now Report Abuse 1) Is the actual result given, which is 0.003, already been multiplied by 100% or no? If not, then the final percentage should be 0.3% which is pretty close to what your average result was. 2) The result CAN be over 100 percent depending on what you're calculating. If you got this percentage from doing a science lab, you will need to state what the possible sources of errors are and etc. Hope this helps!!! eliolin · 8 years ago 1 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse Percentage Of Error

We are working with the ideal gas law and are using the equation PV=nRT. We are calculating molecular weights using MW=(mRT)/PV because n=m/MW. So with that being said, i've calculated several different R values as part of my experiment. However, I also need to find a % error. I keep getting a 122% error. Does this mean my calculations/experiment results are completely wrong? I guess I want to know if 122% is a good percent error or a bad percent error. My values: MW= 116.01 g/mol calculated R (trial 1) = 0.09204 calc R (
a percentage of one (or both) values Use Percentage Change when comparing an Old Value to a New Value Use Percentage Error when comparing an Approximate Value to an Exact Value Use Percentage Difference when both values mean the same kind of thing (one value is not obviously older or better than the other). (Refer to those links for more details) How to Calculate Step 1: Subtract one value from the other Step 2: Then divide by ... what? Percentage Change: Divide by the Old Value Percentage Error: Divide by the Exact Value Percentage Difference: Divide by the Average of The Two Values Step 3: Is the answer negative? Percentage Change: a positive value is an increase, a negative value is a decrease. Percentage Error: ignore a minus sign (just leave it off), unless you want to know if the error is under or over the exact value Percentage Difference: ignore a minus sign, because neither value is more important, so being "above" or "below" does not make sense. Step 4: Convert this into a percentage (multiply by 100 and add a % sign) The Formulas (Note: the "|" symbols mean absolute value, so negatives become positive.) Percent Change = New Value - Old Value × 100% |Old Value| Example: There were 200 customers yesterday, and 240 today: 240 - 200 × 100% = (40/200) × 100% = 20% |200| A 20% increase. Percent Error = |Approximate Value - Exact Value| × 100% |Exact Value| Example: I thought 70 people would turn up to the concert, but in fact 80 did! |70 - 80| × 100% = (10/80) × 100% = 12.5% |80| I was in error by 12.5% (Without using the absolute value, the error is -12.5%, meaning I under-estimated the value) Percentage Difference = | First Value - Second Value | × 100% (First Value + Second Value)/2 Example: "Best Shoes" gets 200 customers, and "Cheap
