To many teachers (and students), assessment simply means giving students tests and assigning them grades. This conception of assessment is not only limited, but also limiting (see section below on Assessment versus grading).
Molecular weight of Nickel(II) Chloride Hexahydrate. Molar mass of NiCl2.6H2O = 237.69108 g/mol. Convert grams Nickel(II) Chloride Hexahydrate to moles or moles Nickel(II) Chloride Hexahydrate to grams. Molecular weight calculation: 58.6934 + 35.453*2 + 6*(1.00794*2 + 15.9994) Note that all formulas are case-sensitive.
Potassium manganate. Potassium manganate is the inorganic compound with the formula K2MnO4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO4), a common chemical. Occasionally, potassium manganate and potassium permanganate are confused, but they are different compounds with distinctly different properties.
