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…Calculate the mass (in g) of 1.00 mol of C13H18O2 (ibuprofen).

Please type answer note write by hend.In today’s experiment, a combination reaction of magnesium and oxygen is used to determine the empirical formula ofmagnesium oxide. After the experiment, I need to answer the fellow two questions: #1; There is one major competitive side reaction that may reduce the accuracy of your results in this experiment. Consult the Internet to research, describe and write a balanced equation for this side reaction. (HINT: What component of air other than oxygen could be responsible?) #2; My Professor asked me match are empirical formula of magnesium oxide from my experiment with the actually one by searching it on the internet. My empirical formula of magnesium oxide from my experiment is Mg4O3 and I look up on the internet is MgO. So, I have to find out why they are different Please help me question #1,2 thank you very much
