What volume would this air occupy at STP?

Homework Statement

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?

Homework Equations

V=nRT/P

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!

Check into Avogadro's law. An ideal gas occupies a specific number of litres per mole at STP.

Ah okay, so I converted wrong. It would be .56 m^3. Thanks!
