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.
Calculate the actual atomic mass of 65Cu. 7) Magnesium consists of three naturally occurring isotopes. these isotopes is as follows: 24Mg (78.70%), 25Mg (10.13%), and 26Mg (11.7%). atomic mass of the three isotopes is 24.3050 amu.
