Ferrous sulfate (FeSO4) 10 mM

MW (heptahydrate) = 278.01

MS 10x = 28mg/L = 0.1 mM - 100 µM

MS 1x = 0.01 mM = 10 µM

make 1,000x for M&S medium = 0.01 M = 10 mM

MW of FeSO4:
Concentration: M
to make: mL
add: g FeSO4

Keep refrigerated

Turns yellow. Probably oxidation. Yellow comes off on a micropore filter.
