What mass of Neon gas is needed to occupy 2.56 L tube at STP?
malfutka [58]

Answer:

Mass = 2.222 g

Explanation:

Given data:

Volume of  neon gas = 2.56 L

Temperature = 273 K

Pressure = 1 atm

Mass of neon gas = ?

Solution:

PV = nRT

n = PV / RT

n = 1 atm × 2.56 L/ 0.0821 atm. L / mol. K× 273 K

n = 2.56 L.atm / 22.4 atm. L/ mol

n = 0.11 mol

Mass = number of moles × molar mass

Mass = 0.11 mol × 20.2 g/mol

Mass = 2.222 g
