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 macro-mineral, which, unlike trace minerals, is needed by the body in large amounts. Calcium, sodium, and potassium are also macro-minerals. The average human body contains about 25 grams of magnesium, one of the six essential minerals that must be supplied in the diet.n its ionic form, magnesium has a positive charge, commonly noted as Mg 2+ . Magnesium cations function as a part of the structure of the body through their presence in bone. But arguably more important is their function as cell regulators in hundreds of chemical reactions throughout the body.
