##### 3 Answers

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 **STP** for the gas laws is

**Given/Known:**

**Unknown:**

**Equation:**

**Solution:** Divide both sides of the equation by

**Answer:**

The volume of **STP** is

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.
