The answer is : V = 2.80x10^-4L.
Gas' properties:
Volume (V)
Pressure (P)
Temperature (T- in Kelvins)
Amount (n - moles)
.
And a Constant R (0.0821 L x atm / mol x K)
The easiest way to solve this problem is to make a set up as follow: !!! STP !!!
V= ? L
P= 1 atm
T= 273 K
n= ?
1) We can get the amount of moles from
Now take :
2)
And that's it !
I strongly hope I was helpful !

You would use the ideal gas law in order to solve this problem. The equation for the ideal gas law is
Given/Known:
Unknown:
Equation:
Solution: Divide both sides of the equation by
Answer:
The volume of
An alternative approach to this problem is by using molar volume at STP.
We know that, at STP, one mole of any ideal gas occupies
The number of moles of
Therefore, since
One can use this method as a primary tool or as a way to double-check the result determined using the ideal gas law.
