hey there, I need to know the formula weight of the product made from 1mmol H2salen + 1mmol nickel (II) acetate tetrahydrate...I then need to determine the quantities (in milligrams) of reactants I will need to use to form the product in the experiment. the product being made is abbreviated to be Ni(Salen) if that helps. If you can, I also need to know the oxidation state of the nickel, the d-electron count, and coordination geometry for the nickel complex being made but this isn't as important as the formula weight and quantity.

Thank you!

chemical formula for H2Salen: C16H16N2O2

H2Salen molar mass: 268 g/mol

Chemical formula for nickel (II) acetate tetrahydrate: NiC4H6O44(H2O)

nickel (II) acetate tetrahydrate molecular weight: 248.7832 Molar mass: 248.8426 g/mol
