Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

Use equation for ideal gas

I am using the ideal gas law with the pressure as 1atm, volume as 1L (5% of 5L), Temperature as 310.15 and R as 8.3145. I get a number for the number of moles and multiply it by 2 since Oxygen is O2. I am not getting the right answer. Does anybody know what I'm doing wrong?

When using 8.314 as your R constant, you have to give Volume in m^3. 5 liters = 0.005 m^3.
If you want to use liters, you must use 0.08206 for your R value.
