Homework Statement



A wine-dispensing system uses argon canisters to pressurize and preserve wine in a bottle. An argon canister for the system has a volume of 55.0 mL and contains 26.0 g of argon. Assuming ideal gas behavior, what is the pressure in the canister at 295 K? When the argon is released from the canister it expands to fill the wine bottle. How many 750.0 mL wine bottles can be purged with the argon in the canister at a pressure of 1.20 atm and a temperature of 296 K?

Homework Equations





The Attempt at a Solution



I was able to solve the first question, but unable to do the second. I tried to solve it by setting the ideal gas equation to n; which, I thought, would represent the number of wine bottles, but it didn't. How do I solve the second question?

Thank you.

How many 0.75L bottles will the decompressed argon fill?

I honestly do not know. I am sorry.

OK, what is the volume of the decompressed argon?

Hi Bashyboy! :smile:

Let's start with the relevant equations.
Did you already have:
PV=nRT?
Molar mass of Argon?

I assumed he solved first part he applied these things. But perhaps I assumed too much...
