Solution Summary: The author explains that the percent error in a medicinal thermometer, which is used at home and by doctors, is to be calculated.
The medicinal thermometer commonly used in homes can be read to
±
0.1
°
F
. whereas those in the doctor's office may be accurate to
±
0.1
°
C
. Percent error is often expressed as the absolute value of the difference between the true value and the experimental value, divided by the true value:
percent error =
|
truevalue-experimentalvalue
|
true value
×100%
The vertical lines indicate absolute value. In degrees Celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of
38.9
°
C

A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.) Fill in the missing part of this equation: (-8.9 x 10^4 N/(C^2x m^2) x ____=? N/(mc^2 x m^2)
A Chemistry 20 student uses a thermometer and a hot plate and measures the boiling point of ethyl alcohol to be 74.1 ºC. Then, she looks in a reference book and finds that the actual boiling point of ethyl alcohol is 78.4 ºC. What is her percent error?Record only your final answer with the correct number of significant digits and the proper units.
