Gas Problem

Question: Tums react in your stomach to produce a gas. The average adult stomach expand to one liter when full. Calculate the pressure in the average adult stomach after taking 2 Tums.

 

I really have no idea where to start on this problem. I know that chemical formula for Tums is CaCO3 and that it reacts with hydrochloric acid in the stomach which is HCl. Since, this is a carbonate-acid reaction, carbon dioxide is the gas produced, correct? Also since I'm looking for pressure and I'm given volume should I use the equation PV=nRT? If so, what would the temperature be? If I don't seem to be headed in the right direction, please help out. Any suggestions would help. Thanks.

I suppose there is no reason a chemistry student (is this a chemistry problem?) would know what the standard human body temperature is, though I would think it handy information for anyone.

 

How about 37oC?

 

But watch the two traps in your gas equation.
