Initial Mass of Oxygen + Mass of Oxygen leaked out

AI Thread Summary
The discussion revolves around calculating the initial mass of oxygen in a tank and the mass that has leaked out, given specific conditions of pressure and temperature. A welder fills a 7.50×10−2 m^3 tank with oxygen at a gauge pressure of 3.00×10^5 Pa and a temperature of 37.1 C, later noting a pressure drop to 1.85×10^5 Pa at 23.4 C. Participants emphasize the importance of showing work in problem-solving to facilitate learning rather than simply providing answers. There is a recognition of the challenges faced by individuals with limited physics background, and encouragement is offered to engage with the material. Overall, the focus is on understanding the process of solving the problem rather than just obtaining the solution.

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.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
