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.
n-Heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is a 100% iso-octane).
