Ideal Gas Law Problem: Solving Pressure & Bottle Purge

AI Thread Summary
The discussion revolves around a homework problem involving the Ideal Gas Law, specifically calculating the pressure of argon gas in a canister and determining how many wine bottles can be purged with it. The first part of the problem was solved, but the second part, which involves calculating the volume of decompressed argon to find the number of 750 mL bottles that can be purged, remains unsolved. Participants suggest using the Ideal Gas Law equation PV=nRT and considering the molar mass of argon to assist in the calculations. Clarification on the steps to solve for the number of bottles is requested, indicating a need for guidance on applying the ideal gas principles correctly. The conversation highlights the challenges of applying theoretical concepts to practical scenarios in gas behavior.

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:

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

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
