Question

What volume would 2.25 moles of Neon gas occupy at STP?

Answer 1

The volume would be 56 L of gas

Answer 2

the volume that occupies 2.25 moles of neon gas in STP conditions is of 50.37L

Step-by-step explanation:

the gas is in STP conditions, this means that it is in standard conditions of temperature and pressure

For standard conditions the pressure has a value of 1atm and the temperature has a value of 273 K

To calculate what volume 2.25 moles of neon gas occupy we use the equation of ideal gases

`P.V=n.r.T`

r (ideal gas constant) =
`0.082(atm.L)/(K.mol)`

we clear the volume

`P.V=n.r.T\\V=(n.r.T)/(P)\\V=(2.25mol.0.082atm.L/K:mol.273K)/(1atm)\\ V= 50.37L`
