Question

How many moles are in 11.5 L of a gas at STP?

Answer 1

0.51mole

Step-by-step explanation:

Given parameters:

Volume of gas = 11.5L

Unknown:

Number of moles = ?

Solution:

Since the gas is at STP,

Number of moles =
`(volume of the gas )/(22.4)`

Insert parameters:

Number of moles =
`(11.5)/(22.4)` = 0.51mole
