What volume does this sample occupy?

[Dx]

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 ive done wrong, pls explain?

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