A sample of neon gas collected at a pressure of L45 atm and a temperature of 15.0 C is found to occupy a velume of 24.3 liters How many moles of Ne gas are in the sample mol Submit Answer Retry Entire Group 2 more group attempts remaining

Answer 1

Answer : The moles of Ne gas are 46.25 moles.

Explanation :

using ideal gas equation

`PV=nRT`

where,

P = pressure of gas = 45 atm

V = volume of gas = 24.3 L

T = temperature of gas =
`15.0^oC=273+15.0=288K`

R = gas constant = 0.0821 L.atm/mole.K

n = moles of gas = ?

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

`(45atm)* (24.3L)=n* (0.0821L.atm/mole.K)* (288K)`

`n=46.25mole`

Therefore, the moles of Ne gas are 46.25 moles.
