Discussion Overview

The discussion revolves around a homework question regarding the calculation of the number of nitrogen (N2) molecules in a 500mL container at a pressure of 780mm Hg and a temperature of 135°C. The focus is on applying gas laws and relevant formulas to solve the problem.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant asks for assistance in determining the number of N2 molecules under specified conditions.
  • Another participant mentions that a mole of gas at standard temperature and pressure (STP) occupies about 22.4 liters and notes the relationship between volume, temperature, and pressure.
  • A third participant suggests that the question should be posted in the Homework & Coursework area and emphasizes the need for the original poster to demonstrate some effort before receiving help.
  • One participant prompts the original poster to consider which formula should be used given the provided variables.

Areas of Agreement / Disagreement

There is no consensus on how to approach the problem, and multiple viewpoints are presented regarding the expectations for homework assistance.

Contextual Notes

Participants have not yet established specific formulas or methods to solve the problem, and there are indications of differing expectations for engagement in the homework discussion.

Can someone please get me started on this one homework question? How many molecules of N2 are in a 500mL container at 780mm Hg and 135 degress celsius?


Thanks

A mole of a gas at STP (0deg C and 1 atmosphere) always occupy the same volume, about 22.4litres.
The volume expands linearly with absolute temperature and decreases linearly with pressure.
Call back if you need more hints.
 
David:
1. Questions like this belong in the Homework & Coursework area (near the top of the forum main page);
2. We typically require you to first show some effort before we can help you.
 
with all the given variables that you are given, what formula should you use?
