How many grams of carbon dioxide are there in a bottle of so

How many grams of carbon dioxide are there in a bottle of soda if the manufacturer bottles beverage at 3 atmospheres of pressure? The ky (Henry\'s law constant) of co, is 3.1 10-2 mol L-atm

Solution

Using Henry\'s law:

p = C/k

Putting values:

3 = C/0.031

So,

C = 0.093 M

Assuming that a soda can has volume of soda equal to 500 mL.

Moles of CO₂ = Molarity*Volume = 0.093*0.5 = 0.0465

Mass of CO₂ = Moles*MW = 0.0465*44 = 2.046 g

Hope this helps !
