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.
What is the number of magnesium atoms that equal to a mass of 24.31 g? Since 24.31g is equal to 1 mole of Mg the answer is 1(6.022 x 10^23) = 6.022 x 10^23 This number is Avogadro's number which tells you how many atoms are in one mole of any ele â¦ ment.
