How many grams of carbon dioxide for 2 liters of 40 degree water at 35 psi?

The calculations never troubled me before today because it just works.

But I'm suddenly tasked with manning the carbonation science booth for at the local neighborhood summer block party and I want to have at least some basic mathematical "science" behind me on the paperboard descriptions.

I'll be having the kids evacuate the air out of 2-1/2 liter soda bottles filled to only 2 liters of 40 degrees Fahrenheit water and then thety will carbonate to about 30 psi but I don't know how many grams of CO2 that is.

Where can I find that calculation given 100% partial pressure of CO2?

1/2 liter of 30psi CO2 for 2 liters of H2O is not going to make very carbonated water, unless that 30psi is maintained for a significant time, like hours, unless broken into very fine bubbles as it is put into the bottles. For my corny kegs, I have to add CO2 many times over several days to get it properly carbonated, or I have to leave the CO2 tank valve open for hours. 1 liter at 30 psi is about 2 liters of CO2 at atmospheric pressure. Most of that pressure will go away by the time the CO2 is dissolved in the water.
