Solving Ideal Gas Law Problem: Volume of Rigid Container at 1.20 atm and 60.0°C

Click For Summary

Homework Help Overview

The problem involves calculating the volume of a rigid container holding a specific amount of gas under given pressure and temperature conditions, using the Ideal Gas Law.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the application of the Ideal Gas Law and question the units being used, particularly the pressure unit and the value of the gas constant R.

Discussion Status

Some participants have provided guidance regarding unit conversions and the appropriate use of pressure units, while others are exploring the implications of using different unit systems. There is an acknowledgment of a misunderstanding regarding the size of the calculated volume.

Contextual Notes

Participants are considering the implications of using atm versus N/m² for pressure and the corresponding units for the gas constant R in their calculations.

Homework Statement



A rigid container holds 2.80 mol of gas at a pressure of 1.20 atm and a temperature of 60.0 degrees Celsius. What is the container's volume?


Homework Equations



PV=nRT

The Attempt at a Solution



(2.80*8.31*333)/1.20 = 6457m^3

This answer seems way too big, what am I doing wrong?

Watch units.
 
Should use N/m^2 rather than atm?
 
Should I**
 
When you write 8.31 for R, what are the units that go with that number?
 
J/mol*K
 
What system of units uses Joules, moles, and Kelvins? Then decide what the units of pressure are for that system of units.
 
Ahhhh okay, I got it now. Thanks!
