What exactly does 40% stand for?
I believe 40% wt./wt. should be 664g MeNH2 in 1L of H2O. (997g/mol (H2O) / 60% * 40%)
This would mean that 1 liter would contain ~21 mols of methylamine. (664g / 31.1g/mol)
The following listing shows that it only should have 12 mol/l.

12 moles per liter would correspond to about 400g, instead of my calculated 664g.
Is "40%" not refering to weight percent or am I missing somethink else?
