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.
The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbonâs molar mass is 12.011 g/mol, and magnesiumâs molar mass is 24.3050 g/mol.he number of grams in the molar mass of an element is the same as the atomic mass. Translating atomic masses into molar masses, you can construct conversion factors that convert between the mass of an element and the number of moles of the element.
