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

Answer:

0.826%

Step-by-step 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 = $\frac{error}{actual measurement}$ x 100

  = $\frac{ 0.018 * 10^{-18} }{2.178 * 10^{-18} }$ x 100

  = 0.826%
