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)

How many milliliters of Cl2 gas must you have to obtain 0.30g at STP in chemistry?

You can use the ideal gas law to solve this problem. First, convert 0.30 g of Cl2 to moles. Then use the molar volume of gas at STP (22.4 L/mol) to determine the volume of Cl2 gas needed. Convert this volume to milliliters (1 L = 1000 mL) to find the answer.


What is the term for a temperature of 0 C and a pressure of 1 ATM?

The term for a temperature of 0°C and a pressure of 1 ATM is "standard temperature and pressure" (STP). STP is often used as a reference point in chemistry and physics to describe the behavior of gases and to facilitate comparisons of experimental data. At STP, one mole of an ideal gas occupies a volume of 22.4 liters.


What is the volume occupied by 20.4 liters of co2 at 1200 torr when it is STP?

To find the volume occupied by 20.4 liters of CO2 at STP (Standard Temperature and Pressure, defined as 0°C and 1 atm), we can use the ideal gas law and the concept of proportionality. At STP, 1 mole of gas occupies 22.4 liters, and 1200 torr is approximately 1.58 atm. Using the combined gas law, we can calculate the volume at STP: [ V_{STP} = V_{initial} \times \frac{P_{initial}}{P_{STP}} \times \frac{T_{STP}}{T_{initial}} ] Substituting the known values, the volume at STP will be approximately 12.9 liters.
