Expert Solution

You can use Avogadro's law to explain this: This law describes how, under the same condition of temperature and pressure, equal volumes of all gases contain the same number of molecules. This law can be expressed as it follows:

Combining this law with the Boyle Mariotte Law

This is called combined equation (it is not its full expression as the temperatura can also be included) that can demonstrate why the quantity of products can be known just knowing the pressure of the gas or gases in any particular formula, you already knew volume and mass, you can easily calculate quantity in moles. The volume of any particular gas is always proportional to the amount of partial pressure that particular gas makes of the total pressure, that is why the products can be equaled to the pressures when we are talking about gases and why you can use the Kc or Kp independently to calculate gas concentration
