Trivial Ammonia recipe is an imperfect ratio

[MrMagolor]

Mixing ammonia, with 5 nitrogen and 15 hydrogen, leaves something like 7.0182461e-08 nitrogen when transferring 10u of diethylamide. Now, the chemicompiler decides that in a beaker with a hundredth of a millionth of a unit above 90, you can't transfer 10 units. This isn't an issue for normal chem mixing, since you can just remove all.
