The example shown is for sodium chloride, NaCl. The molar mass is the massof 1 sodium (22.98g/mole) and 1 chlorine (35.45g/mole) added together, 58.43g/mole. If theformula shows multiple atoms, as in sugar, you must take that into account. For sugar, it will be12 times the mass of a carbon atom plus 22 time the mass of hydrogen atom, plus 11 times themass of oxygen atoms.The calculation of moles will be similar to that done in the previous…
