Answer to Question #139141 in General Chemistry for kaitlynn adkins

Question

A student’s calculation was found to have a 19.7% error, and the actual value should have been 25.7 mL. What are the two possible values for the student’s experimental measurement?

Answer 1

Proportion:

25.7 — 100 %

x — 19.7 %

x = 5.06 mL

Possible values for the student’s experimental measurement:

25.7 + 5.06 = 30.76 mL

25.7 — 5.06 = 20.64 mL

Answer: 30.76 mL and 20.64 mL
