Discussion Overview

The discussion revolves around calculating the equivalent gas volumes using Avogadro's Law, specifically comparing the volumes of methane (CH4) and nitrogen (N2) under different conditions of temperature and pressure. The context is primarily homework-related, focusing on the application of gas laws.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant presents a homework problem involving the calculation of gas volumes using Avogadro's Law and expresses uncertainty about the appropriate equation to use.
  • Another participant suggests using the ideal gas law equation, PV = nRT, as a potential approach.
  • A third participant acknowledges attempting to use the ideal gas law but indicates confusion over the correct value for moles.
  • Another reply clarifies that a ratio of the ideal gas law can be used, implying that the constant R does not need to be specified for the calculation.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best approach to solve the problem, as there are differing levels of understanding and application of the ideal gas law.

Contextual Notes

There is a lack of clarity regarding the specific values to be used for moles and the implications of the different conditions (temperature and pressure) on the calculations.

Homework Statement


What volume of CH4 at 0°C and 1.00 atm contains the same number of molecules as 0.58 L of N2 measured at 35.0 °C and 1.50 atm?


Homework Equations


I think you just need to use Avogadro's Number and multiply by the molar mass?
I guess my question is what equation would you use?

The Attempt at a Solution


I haven't attempted the question due to lack of an equation.

You are probably looking for PV = nRT
 
thank you. i was trying that formula but was plugging in the wrong number for moles.
 
Remember you are doing the ratio of two of these, so you don't actualy need a value for R
