STP stands for standard temperature and pressure. Because gases occupy different volumes at different temperatures and pressures, it is necessary to define a set of conditions that can be considered standard.

At STP:

  • The temperature is 0°C or 273 K
  • The pressure is 1 atmosphere or 760 mmHg or 760 torr
  • One mole of any gas occupies 22.4 L of volume (molar volume)

this describes the conditions that are most likely to be in your lab.its not too likely that your lab would be under 10 atmospheres of pressure,or wolud be heated to 40 celsius.STP also is a set of figures that can be used by everyone,if we had no common factors for the calculations then every time you calculated somthing you would have to work out very slight alterations in temprature and pressure even though they would have virtually no impact on the calculation,STP makes the calculations more convienent
