of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Finding molar mass starts with units of grams per mole (g/mol). What is the mass number of the isotope zinc - 65?a. 30b. 65c. 35d. 95 Zinc is a chemical element with atomic number 30 which means there are 30 protons and 30 electrons in the atomic structure.

Thus number of neutrons in dipositive zinc ion with mass number 70 is 40. 65 atomic mass units Zinc has 30 protons and 35 neutrons, so its overall mass
