What is the volume occupied by 24.4 g of argon gas at a pressure of 1.31 atm and a temperature of 464 K?

n=24.4g P=1.31atm T=464 Find V

i tried working it out and i got 7091.98 and is inncorrect can i get some help?

n is not 24.4g . n is the number of moles, in this case, n=24.4g/molmassArgon

find n, as I laid out.

PV=nRT

solve for V

(1.31)(V)=(24.4)(464)

and i got 11320 ? is that correct?

No. As Bob Pursley told you, n is NOT 24.4. AND he told you to calculate n.
