1. The problem statement, all variables and given/known data A 12.0 cm-diameter compressed-air tank is 50.0 cm tall. The pressure at 30.0 C is 110 atm . What volume would this air occupy at STP? 2. Relevant equations V=nRT/P 3. The attempt at a solution The first question asked to find the amount of moles of air in the tank, and got it right with an answer of 25. So I plugged in: (25mols)(.0821)(273K)/(1*10^5) And got .0056 m^3, but that seems to be wrong. Any help would be appreciated. Thanks!
