Use the Ideal Gas Law PV=nRT Here's the integer variables: (1)(22.4)=n(0.0821)(273) [FYI: gas constant changes depending upon the units used, so in this case I had used atmospheres, liters and kelvin -- L atm K−1 mol−1 -- which calls for the number you see at variable R.] In the example above (for the nitrogen gas) you would solve for variable n. In this case n=1.00059375 You could round that, but that's your volition -- probably not a good idea. Keep in mind that nitrogen and chlorine are diatomic gases and ammonia is a compound. I'm not gonna do your homework for you, but the sites I referenced (in the sources below) will help you if you get confused. Trust me, learning this stuff is a lot more helpful to you than just seeking out blatant answers.

Hi there, I’m sorry to hear that you have become so self-conscious about this mole. The first thing you need to realize is that it is probably not nearly as noticeable to others as it is to you. This is often the case because we spend so much time analyzing our own image in the mirror. I would not recommend any over-the-counter mole removal treatments for several reasons. Most importantly, before attempting any type of removal or treatment for a mole, it is important to ensure that it is benign. A trained dermatologist usually can visually inspect a mole and let you know if there is any skin cancer risk. These topical remedies can also lead to scarring and leave behind changes in skin pigmentation. However, most likely they will just not be effective. For most people who desire removal of moles for cosmetic purposes, it is because they are raised. If that is the case, there is a very simple procedure called a “shave biopsy” that shaves the mole flat without having to surgically excise the entire mole. It will leave behind a flat scar, that most people prefer to the raised mole. A dermatologist can provide the procedure, it is relatively painless and takes about 10 minutes. This will also be less expensive and leave a smaller scar than a full surgical excision. I hope this helped you in some way!

I remove my own skin tags unless they are big enough to need a stitch, most are not. Moles are to be removed bt a doctor. I remove mine, sisters and a friends skin tags with a tiny pair of cutical scissors. I am not telling you to do it, just saying it can be done. It is what the doctor will do and charge you for it. Your body, your choice.
