Final answer:
To calculate the percent error, subtract the accepted value from the experimental value, take the absolute value, divide by the accepted value, and multiply by 100%.
Step-by-step explanation:
To calculate the percent error, we need to compare the experimental value with the accepted value. In this case, the experimental value is 4.70 grams and the accepted value is 4.55 grams. To calculate the percent error, we use the formula:
Percent Error = (|Experimental Value - Accepted Value| / Accepted Value) x 100%
So, the percent error is: (|4.70 grams - 4.55 grams| / 4.55 grams) x 100% = 3.30%.
