What is the volume of 0.2 moles of neon gas at stp?

4.5 L

Explanation: Ideal gas at STP standard temperature and pressure: at STP

P = 1 atm

T = 1 °C convert to K (273 K)

Solution:

PV= nRT

Derive the equation to find V

V= nRT / P

Substitute the values

V= 0.2 moles x 0.082 L.atm/ mol. K x 273 K / 1 atm

Cancel out the units of moles, atm and K so the remaining uni is in L.
