Ideal Gas Law Problem: Solving Pressure & Bottle Purge

Click For Summary

Discussion Overview

The discussion revolves around a homework problem related to the Ideal Gas Law, specifically focusing on calculating the pressure of argon in a canister and determining how many wine bottles can be purged with the gas once released. The scope includes theoretical application of gas laws and problem-solving techniques in a practical context.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • The initial post presents a problem involving the Ideal Gas Law and seeks assistance with calculating the number of wine bottles that can be purged with argon after it is released from the canister.
  • One participant asks for clarification on how many 0.75L bottles the argon can fill.
  • Another participant expresses uncertainty about the problem and offers no solution.
  • A participant requests the volume of the decompressed argon to further the discussion.
  • Another participant suggests starting with the relevant equations, specifically mentioning PV=nRT and the molar mass of argon, indicating these are essential for solving the problem.
  • There is a suggestion that assumptions may have been made regarding the initial participant's understanding of the problem.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants expressing varying levels of understanding and uncertainty regarding the calculations needed to solve the problem.

Contextual Notes

There are limitations in the discussion, including potential missing assumptions about the ideal gas behavior and the specific conditions under which the argon is released and used.

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 like Serena said:

PV=nRT?
Molar mass of Argon?

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