We're being asked to determine the number of moles of CO2 dissolved in 355 mL of soda after the soda has gone flat.
Recall that the solubility of a gas is given by Henry’s law:
Sgas = solubility of the gas (in mol/L or M)
kH = Henry’s law constant for the gas
Pgas = partial pressure of the gas
Also recall that molarity is given by:
For this problem, we need to do the following steps:
Soft drinks are canned under 4 atm of CO2 and release CO2 when the can is opened.
(a) How many moles of CO2 are dissolved in 355 mL of soda in a can before it is opened?
(b) After the soda has gone flat?
