Answer:
455.674g/mol
Explanation:
Molar Mass Calculation
To calculate the molar mass of any molecule, you would require a periodic table next to you. Each number next to the element represents the number of moles of that element, or simply the number by which you multiply the molar mass of that atom by. On the periodic table, under each element symbol is the mass of the atom, usually accompanied by 3 decimals.
Carbon (C) = 12.011g/mol
Hydrogen (H) = 1.008g/mol
Oxygen (O) = 15.999g/mol
Zinc (Zn) = 65.38g/mol
In the molecule you have 12 C, 22 H, 14 O and 1 Zn, now all you have to do is multiply the given molar masses of each atom by each respective number of atom and do the sum
12(12.011) + 22(1.008) + 14(15.999) + 65.38 = 455.674g/mol
