# What volume (in liters) does 2.895 moles of oxygen occupy at STP?

At STP, 2.895 moles of

Since we are at STP and are given only one set of conditions, we have to use the ideal gas law equation:

I should mention that the pressure does not always have units of atm, it depends on the units of pressure given in the gas constant.

List your known and unknown variables. Our only unknown is the volume of

At STP, the temperature is 273K and the pressure is 1 atm.

Now we have to rearrange the equation to solve for V:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
