Question

a flask contains 0.83 mol of neon gas at a temputure of 35 degrees celcius. the pressure gauge indicates 0.37 atm inside the flask. what is the volume of the neon gas?

Answer 1

Answer: The volume of neon gas is, 56.7 L

Explanation :

To calculate the volume of gas we are using ideal gas equation:

`PV=nRT`

where,

P = Pressure of neon gas = 0.37 atm

V = Volume of neon gas = ?

n = number of moles neon = 0.83 mole

R = Gas constant =
`0.0821L.atm/mol.K`

T = Temperature of neon gas =
`35^oC=273+35=308K`

Now put all the given values in above equation, we get:

`0.37atm* V=0.83mole* (0.0821L.atm/mol.K)* 308K`

`V=56.7L`

Therefore, the volume of neon gas is, 56.7 L
