Calculate the volume, that is easy: 

<span>4 x 5 x 2.5 = 50m3 </span>

<span>now, as you did not provided if you use nitrogen in </span>

<span>ntp (normal temperature and pressure - 20c, 1atm) weight is 1.165kg/m3 </span>

<span>or: </span>

<span>stp (standard temperature and pressure - 0c, 1atm) weight is 1.2506 </span>

<span>these are in case of pure nitrogen, as in presented case nitrogen is only 79% we need to change weights to represent that: </span>

<span>ntp - 1.165kg/m3 / 100% x 79% = 0.92035kg/m3 </span>

<span>stp - 1.2506kg/m3 / 100% x 79% = 0.987974kg/m3 </span>

<span>therefore in case of: </span>

<span>ntp, total weight of n2 will be 50m3 x 0.92035kg/m3 = 46.0175kg </span>

<span>stp, total weight of n2 will be 50m3 x 0.987974kg/m3 = 49.3987kg</span>
