Which law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant? boyle’s law dalton’s law charles’s law avogadro’s law

Avogadro’s law states that the volume of a gas is proportional to the number of moles of the gas when pressure and temperature are kept constant

However, this is a valid statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules

They are the laws which relates the volume, pressure and temperature of a gas. The gas laws includes:

Therefore, the law which states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant is Avogadro's law

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
