Ha! There's one half sulfuric acid molecule complexed with every N-methyl-p-aminophenol! :^)

By the way, 41.8/344.38= 0.121 moles, and not 0.125 moles. So you don't actually have a full 1/8th mole.

Even then, 0.125 moles of K2SO4 (MW = 174.26) should equal 21.78 grams.

But we're splitting hairs.
