Issued as a cumulative or non-cumulative L/C, the former allows for unused credit amounts to rollover into subsequent periods while the latter maintains a fixed amount of credit available each period.
average atomic mass of magnesium is 24.3 g/mole so 24.3 X 1.56 X1021 / 6.02 X1023 = .063 grams.
Magnesium is a silver white metal and the eighth abundant element in the universe by mass. Constitutes about 1,92% of the earthâs crust (magnesium oxide) and is also found in seawater (magnesium salt). Magnesium is the 12 th element on the Periodic Table, the lightest among the metals for structural application. Magnesium is not found in a pure form because it bonds with other elements. Itâs necessary to apply a process to retrieve a usable amount of Mg. The two most important sources are natural minerals like Dolomite and Magnesite. Dolomite is a Calcium Magnesium Carbonate compound.
