Question

how many grams of carbon dioxide gas is dissolved in a 1 l bottle of carbonated water if the manufacturer uses a [ressire pf 2.4 atm in the bottling process at 25 degree celcius. KH for CO2=29.76 atm/mole/L at 25 degree celcius?

​

Answer 1

We know the equation.

P= KHc

Where P =2.4 atm , KH = 29.76 atm/mole/L

Therefore, C = P/KH

  = 2.4 /29.76

  = 0.08 mol/L of CO2

To convert into grams, 1 mole of CO2

= 12 + (16 x 2) = 44g

Mass of CO2 in grams  = mol of CO2 x 44 g/mol

  = 8.06 x 10-2 x 44

  = 3.52 g of CO2 is dissolved in 1 L of carbonated water
