Question

During the analysis of ascorbic acid in a 500 mg Vitamin C tablet a student found the tablet actually contained 487 mg. What is the percent error?

a)97.4%

b)2.60%

c)13.0%

d)1.02%

Answer 1

The percent error is calculated using the difference between the experimental value and the theoretical value divided by the theoretical value, multiplied by 100%. For the ascorbic acid content in the Vitamin C tablet, the percent error is 2.60%.

Step-by-step explanation:

To calculate the percent error of the ascorbic acid content in the Vitamin C tablet, we can use the following formula:

Percent Error = (|Experimental Value - Theoretical Value| / Theoretical Value) × 100%

In this case:

• 
  
• 
  
• 
  

Applying the values to the formula:

Percent Error = (|487 mg - 500 mg| / 500 mg) × 100% = (|13 mg| / 500 mg) × 100% = 2.60%

Therefore, the percent error is 2.60%, which corresponds to option b) 2.60%.
