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

Answer:

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

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) =$0.082\frac{atm.L}{K.mol}$

we clear the volume

$P.V=n.r.T\\V=\frac{n.r.T}{P}\\V=\frac{2.25mol.0.082atm.L/K:mol.273K}{1atm}\\ V= 50.37L$
