The expression below was formed by combining different gas laws. mc007-1.jpg which law was used to determine the relationship between the volume and the number of moles in this equation? boyle’s law charles’s law avogadro’s law gay-lussac’s law

Avogadro’s law

Avogadro’s law

Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Mathematical definition

The law can be written as:

V ∝ n or   V/n = k

where

V is the volume of the gas;

n is the amount of substance of the gas (measured in moles);

k is a constant for a given temperature and pressure.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
