When the syringe is at zero volume, why does the pressure gauge read 1.0 atm?

What about the volume of the tubing, Vtube?
18
19
We can double the volume, by pulling the pison on the syringe,
20
until the pressure drops to half the gauge value.
21
22
Pgauge x Vtube = (Pgauge/2) x Vtotal
23
Vtotal = 2 x Vtube = Vtube + Vsyringe
24
therefore Vsyringe = Vtube
