1. What volume is required to contain 100.0 mol O2 at STP?

Colt1911 [192]

Answer:

The volume is 2238,6 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= 100 mol x 0,082 l atm/K mol x 273K/ 1 atm

<em>V=2238, 6L</em>
