I need to calculate the mass of CO2 produced in the reaction of NaHCO3 + HCl

Data
Mass of NaHCO3 = .05g
Mass of system before reaction 117.9 g
Mass of system after reaction 117l98
Maxium pressure 1.4094
initial pressure 1.0094
pressure change .4
temp 299.2K

No idea what the set up was.
max P = 1.4094 what?
initial P = what unit?
atmosphere probably.
Did the system gain weight? If so due to what?
