PERCENTAGE ERROR Name Percentage error is a way for scientists to express how far off a laboratory value is from the commonly accepted value. The formula is: Accepted Value - Experimental Value % error x 100 Accepted Value absolute value Determine the percentage error in the following problems. 1. Experimental Value 1.24g 30 1,2d 98 Accepted Value = 1.30 g Answer: 20 2. Experimental Value 1.24x 102 g Accepted Value 9.98 x 10 g Answer: 3. Experimental Value 252 mL Accepted Value 225 mL Answer: 4. Experimental Value 22.2L Accepted Value = 22.4 L 0M Answer: 5. Experimental Value 125.2 mg Accepted Value = 124.8 mg Answer: @instructional Fair, In 11 Chemlstry IF8766
