#### Explanation:

Because we are at standard temperature and pressure and are given only one set of conditions, we can 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.

- Number of moles

- Temperature

- Pressure

Volume of

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

Let's rearrange the equation to solve for V:
