Question

What is the number of moles in 526 L O2 at STP?

Answer 1

526 L O2 x 1 mol O2 / 22.4 L = 23.5 mol O2

Answer 2

Answer: The correct answer is : 23.5 mol of O2 .

At STP ( Standard Temperature and potential ) 1 mole of gas has 22.4 L of volume .The follow can be expressed as :

`Mole = (given volume in L)/(22.4 L ) * 1 mol`

Given volume of O2 gas = 526 L

Plugging value in the formula :

`Mole = (526 L)/(22.4 L) * 1 mol`

Mole of O2 gas at STP = 23.5 mol
