Question

Please help!?!

5.Tin’s actual atomic radius is 140 pm. Use the math equation below to determine the percent error of your estimated value. (2 points)

Percent error = × 100
This equation means that you subtract to find the difference between the actual value (given in this problem) and the experimental value (estimated from the graph). The numerator is in an absolute value sign, so the difference should always be positive. Take that difference and divide by the actual value (given in this problem) of tin’s atomic radius . Take your answer and multiply by 100 to make it a percentag

5.Tin’s actual atomic radius is 140 pm. Use the math equation below to determine the percent error of your estimated value. (2 points)

Percent error = × 100
This equation means that you subtract to find the difference between the actual value (given in this problem) and the experimental value (estimated from the graph). The numerator is in an absolute value sign, so the difference should always be positive. Take that difference and divide by the actual value (given in this problem) of tin’s atomic radius . Take your answer and multiply by 100 to make it a percentage, and that is your percent error. Percent error is a common calculation in science. Your grade will not be determined by the amount of error, but just that you used the calculation correctly.
6.The atomic radius you estimated from your graph is most likely not exactly the same as the true atomic radius of tin. There is a small percent error. What do you think caused this error? (2 points)
