HCL: 45 ml
Zn: 0.100 g
pressure before zinc was added to HCL: 1.000 atm
pressure after: 1.138 atm
temp before: 21.5 C
temp after: 22.3 C
volume in gas syringe: 36.81 ml
experiment 2
HCL: 45 ml
Zn: 0.200 g
pressure before zinc was added to HCL: 1.000 atm
pressure after: 1.277 atm
temp before: 21.5 C
temp after: 23.0 C
volume in gas syringe: 73.64 ml
