Molarmass Fe 55 g/mol & density 7.9g/cm^3.It means that volume i.e. 55/7.9 cm^3 must contain 6.022 ×10^23 atoms.why does 22.4L contain th8 no of atom?
Why is it that 22.4L of any gas contains the same number of atoms as in 55/7.9 cm^3?
22.4 L of any gas at standard temperature and pressure conditions contains roughly 6.022 x 10^23 atoms or molecules. This is due to the Avogadro's Law which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules or atoms.
