Homework Help Overview

The discussion revolves around calculating the volume occupied by a sample of C@2 containing 3.01x10^23 molecules at standard temperature and pressure (STP). Participants are exploring the application of the ideal gas law in this context.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the ideal gas law equation, P*V=n*R*T, and the variables involved. There is confusion regarding the correct interpretation of 'n' as the number of moles versus the number of molecules.

Discussion Status

Some participants have provided guidance on the ideal gas law and pointed out the error in using the number of molecules instead of moles. There is an ongoing exploration of the implications of this misunderstanding.

Contextual Notes

Participants are working under the constraints of homework rules, which may limit the amount of information they can share or the methods they can use. The original poster expresses uncertainty about their previous calculations and seeks clarification.

A given sample of C@2 contains 3.01x10^23 molecules at STP. what does the samle occupy?

Im not going to put down all the formulas i used since i got this wrong on a test question, can anyone tell me what answer they came up with. I said 22.4L using V = .5mol/23.4mol/L= 22.4L or something to that effect.

P*V=n*R*T

You're given P,T,n, and R is a constant. Solve for V.

I tried enigama and got it wrong. What did i do wrong?

T = 273K
R = 8.315 J/mol*K
P 1.013 x 10^5
n = 3.01 x 10^23

V= nRT/P but my answer is wrong can you figure out what I've done wrong, pls explain?

Here's your problem. n is supposed to be the number of moles, but you inserted the number of molecules.

O gosh, what a dummie I am!
Thanks you guys rule!
