Homework Help Overview

The discussion revolves around calculating the volume of 1 mole of steam at 100°C and 1 atm pressure, using the ideal gas equation PV=nRT.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss rearranging the ideal gas equation to solve for volume, with some expressing uncertainty about the simplicity of this approach. There are requests for clarification on whether their reasoning is correct.

Discussion Status

The conversation includes attempts to validate the use of the ideal gas law for this scenario. Some participants affirm the assumption of treating steam as an ideal gas, while others seek reassurance about their approach.

Contextual Notes

There is a noted concern about the validity of the ideal gas assumption for steam at the given conditions, as well as a request for guidance without direct answers.

Homework Statement


Calculate the volume of 1 mol of steam at 100°C and a pressure of 1 atm assuming that it is an ideal gas.

Homework Equations


PV=nRT

The Attempt at a Solution


Well, if I am honest I was just going to re arrange the above equation for V and plug the numbers in but that seems far too easy so I assume I am wrong.

Can someone clarify that I am wrong and just give a gentle push in the right direction please?

Thank you!

Assume so.

Assume so.

I did that when I said I would use PV=nRT though?
