Problem- A soft drink is made by dissolving CO2 gas at 4.00 atm in a flavored solution and sealing the solution in aluminum cans at 20.°C. What amount (in moles) of CO2 is contained in a 360-mL can of the soft drink? At 20.°C the Henry's law constant for CO2 is 2.3 x 10-2 mol•L-1•atm-1.
Please be very comprehensive in your answer and do not omit any steps
