Constant Temperature, Sample Data and Analysis
V
0
= 3.6 cc
Among different lab groups or over several trials you may find that calculated values of V
0
vary
by 1 cc or more. This may look like a very large uncertainty, but, since it is added to the total
volume of gas (40 to 60 cc) the absolute uncertainty, rather than the relative uncertainty, should be
considered.
