36 A student measured the melting point of a sample of gallium to be 309 K. Based on Table S, which numerical setup can be used to calculate the student’s percent error?
Explanation: Table T on the Reference Table provides us with a formula for piercer error calculation which is equal to (measured value – accepted value)/ accepted value × 100%. Student's melting point is the measured value. We can find the accepted melting point of gallium in table S.
