    Preparing a Methylene Blue solution. Need MB Equivalent Weight.

    Hello, I need to prepare a Methylene Blue solution (1ml = 0.01 meq), or 0.01N, from powder. To calculate the amount of powder required I need the Methylene Blue's equivalent weight or equivalent numbers, but haven't been able to find it so far. Does anyone know? Help appreciated.

    Latex or an equivalent?

    Is it possible to have a mod installed to make it easier / possible to write chemical equations? EG: 2CH3CH3 + 7O2 -> 6H2O + 4CO2 That's fairly confusing :(
