What is the molar mass of magnesium (Mg)? A 12.00 g/mol B 22.99 g/mol C 24.31 g/mol D 26.98 g/mol

C 24.31g/mol

Explanation:

if you look at the periodic table, than when you look at the element magnesium (Mg) it is 24.305 in atomic mass which rounds up to 24.31

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
