The typical partial pressure of the carbon dioxide in the atmosphere is 0.0004 atm. in the small gas volume inside a bottle of a carbonated beverage the pressure of the carbon dioxide is 2 atm (this varies widely). what is the ratio of the concentration of carbon dioxide dissolved in the soda before opening (with 2 atm pressure) to post-opening when the carbon dioxide concentration has come to equilibrium with the carbon dioxide in the environment (gone flat)?

The ratio is 1:5000

Explanation:

The high content of carbon dioxide in soda produces in consumer sensations of refresh and good tasting.

A ratio is a relationship between two numbers indicating how many times the first number contains the second.

Thus, the ratio of carbon dioxide before opening to post-opening is:

0,0004 atm/2 atm= 5000

I hope it helps!

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
