Question

A student obtained the Rydberg constant to be 2.16*10-18 J. What is the % error of the measurement? Answer as percentage and keep one decimal place. For example, if your answer is 12.5%, please either use 12.5% or 12.5. The fraction 0.125 will NOT be counted as correct answer.

Answer 1

0.826%

Explanation:

The Rydberg constant = 2.178 ×
`10^(-18)` J.

students record = 2.16 x
`10^(-18)`J.

error = 0.018 x
`10^(-18)`J.

Percentage error =
`(error)/(actual measurement)` x 100

=
`( 0.018 * 10^(-18) )/(2.178 * 10^(-18) )` x 100

= 0.826%
