Avagadto's Law (one of the Gas Laws) states that the volume of gas is directly porportional to the number of molecules of gas.  This law assumes that pressure and temperature are constant.

$$\large{ n = \frac{ m }{ \mu } }$$

Where:

$$\large{ m }$$ = mass

$$\large{ n }$$ = number of moles of the gas

$$\large{ \mu }$$  (Greek symbol ) = gas molecular weight

$$\large{ v }$$ = mole volume

$$\large{ V }$$ = total volume of the gas

Solve for:

$$\large{ n = \frac{ V }{ n } }$$
