Results table. To clean up, zoom out from the balance and drag the sample to the red disposal container. Repeat with ammonium chloride (NH4Cl), located on the Salts shelf. C12H22O11 NH4ClMass (g) 1.0481 g 1.0444g Molar Mass (g/mol)MolesMoles of each elementAtoms of each element Much like the previous calculation, you will use the periodic table to determine the molar massof the compound. 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…
