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.
