Problem 18PE

Express your answers to problems in this section to the correct number of significant figures and proper units. (a) How many significant figures are in the numbers 99 and 100? (b) If the uncertainty in each number is 1, what is the percent uncertainty in each? (c) Which is a more meaningful way to express the accuracy of these two numbers, significant figures or percent uncertaintie

Step-by-Step Solution:

Solution 18PE: Step 1 of 7 (a) Calculate the number of significant figures for each of the numbers. Consider the two numbers are .99 and 100 99 has 2 significant figures. 100 has 1 significant figures. Therefore, has significant figures and has significant figure. Comment Step 2 of 7 (b) The formula to find the percent uncertainty is, A % uncertainty = A × 100 Comment Step 3 of 7 Now, for number 99 A = 1 A = 99 Comment Step 4 of 7 Substitute for and for . % uncertainty = 1 × 100 99 = 1.0% Comment
