Overall Conversion Clarification

[blehxpo]

So I have a Recycle and Purge, of Haber Process
N2 + 3H2 --> 2 NH3

And it tells me that the Overall Conversion of N2 to NH3 96

I know that the overall conversion formula is

moles fed - moles produced / moles fed

For this case moles fed of N2 is 23.75 mol/s
So is it just

23.75 - moles NH3 produced / 23.75 = .96

0.95 moles NH3 produced

or

23.75 - moles NH3 produced / 23.75 = 0.04


22.8 moles NH3 produced
