Avogadro's Law

According to Avogadro's gas law, when temperature and pressure are held constant, the volume of a gas is proportional to the number of moles of gas present.

 

Avogadro's Law formula

\(\large{ \frac {V_i} {n_i} =  \frac { V_f  }   {  n_f }  }\)

Where:

\(\large{n_i  }\) = initial number of moles

\(\large{n_f }\) = final number of moles

\(\large{V_f }\) = final volume
