Initial Mass of Oxygen + Mass of Oxygen leaked out

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving the calculation of the initial mass of oxygen in a tank and the mass of oxygen that has leaked out. The scenario includes specific parameters such as the tank's volume, initial gauge pressure, and temperature changes affecting the gas behavior.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants express a desire to understand the process of solving the problem rather than receiving direct answers. There are attempts to clarify the expectations for showing work and the importance of making an effort in the learning process.

Discussion Status

The discussion is ongoing, with some participants seeking guidance on how to approach the problem while others emphasize the necessity of demonstrating attempts at solving it. There is a recognition of the challenges faced by the original poster, and a supportive tone is present in the responses.

Contextual Notes

The original poster indicates a lack of background in physics, which may influence their understanding of the problem. There is an emphasis on the need to show work as part of the homework help process.

Homework Statement



A welder using a tank of volume 7.50×10−2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol) at a gauge pressure of 3.00×105 Pa and temperature of 37.1 C. The tank has a small leak, and in time some of the oxygen leaks out. On a day when the temperature is 23.4 C, the gauge pressure of the oxygen in the tank is 1.85×105 Pa.

Homework Equations



Find the initial mass of oxygen.
Find the mass of oxygen that has leaked out.

You need to show some work and where you are having a problem.

Homework Help doesn't mean that it gets done for you.

I see 5 problems you've posted and apparently no work.
 
Hey...I'd love to show some work...and I don't intend on anyone giving me the answers...I just want to know how its done...I've been enrolled in a really hard physics course that I can't get out of...and back in high school my physics class was a joke...so basically I have no background whatsoever...My sincere apologies if I caused any trouble.
I think I'll just remove my threads...

Thanks anyways...

It's no trouble, if you just show some work and make an attempt.

The idea is that you learn.
