Question

How many moles of nitrogen gas will occupy a volume of 5L at 3.85 atm and 27c?

Answer 1

`n=0.78mol`

Step-by-step explanation:

Hello there!

In this case, according to the given information, it possible for us to realize that this problem is solved via the ideal gas equation:

`PV=nRT`

By which we solve for n (moles) as shown below:

`n=(PV)/(RT)`

Then, we plug in the given pressure, volume and temperature (in K) to obtain:

`n=(3.85atm*5L)/(0.08206(atm*L)/(mol*K)*(273+27)K) \\\\n=0.78mol`
