Problem: 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?

FREE Expert Solution

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=kH·Pgas

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:

Molarity (M)=moles of soluteLiters of solution 


For this problem, we need to do the following steps:
