A scientist needs to store 28.0 moles of xenon gas at STP in the lab. What size gas tank

will he need?

376 L

473 L

628 1

219 L

We need a volume tank size equal to 628 L

Explanation:

We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273K of temperature.

PV=nRT V = (nRT) / P

V = (28 mol x 0,082 l atm/K mol x 273K) / 1 atm = 626, 808L
