Avogadros law is the relation between volume and number of moles at constant T and P. V 2 6 L T 1 150 K. At a fixed volume the temperature and pressure of a gas are directly proportional to each other.
To Determine the Pressure of the Gas.
The simplest mathematical formula for the combined gas law is. To understand how to determine the appropriate formula for a given gas law problem One mole of an ideal gas is sealed in a 224-L container at a pressure of 1 atm and a temperature of 273 K. Use the ideal gas law equation and derive a formula that relates pressure and number of moles of gas at constant temperature and volume. We can also derive combined gas law from the ideal gas equation.
