Hi :)
The chemical formula for nitrogen gas is N2.
Nitrogen gas is one of the diatomic elements, in which one molecule consists of two atoms of the same element bonded by one or more covalent bonds.
The angle for each complete revolution is 2π radians (that's 360°).
So . . .
Time = (18 revs) x (2π radians / rev) x (1 sec / 1.7π radians)
Time = (18 · 2π · 1 / 1.7π) (rev ·radian · sec / rev · radian)
<em>Time = 21.18 seconds</em>
