A tank contains 115 miles of neon gas. It has a pressure of 57 atm at a temperature of 45 c. Calculate the volume of the tank.
Elena-2011 [213]

Answer:

Volume occupied by  Neon gas is 52.67 L

Explanation:

Using Ideal Gas Equation:

PV = nRT

where

P = pressure exerted by the gas = 57 atm

V = volume occupied = ?

n = number of moles = 115 moles

R = Ideal gas constant = 0.0821 L.atm/K.mol

(R value should be taken according to the units of Temperature,pressure, volume and mole)

T = Temperature = 45 + 273 = 318 K

(For temperature conversion from C to K add 273 to temperature:T + 273)

PV = nRT , So

V = \frac{nRT}{P}

Put values of T,P,n,R

V = \frac{115\times 0.0821\times 318}{57}

V = \frac{3002.39}{57}

V = 52.67 L

Volume occupied by 115 moles of Neon gas at 57 atm Pressure and 45 C temperature is 52.67 L
