This problem is describing the molecular formula of Metformin as an oral diabetes medicine to control the blood sugar levels and is asking for the molar mass, moles in a single tablet and the total moles Jennifer consumes in a daily treatment. The results are 129.164 g/mol, 0.003871 mol and 0.02323 mol, respectively, according to the following work:
Firstly, we the molar mass of metformin, we multiply the subscript of each atom by its atomic mass and then we add them up as shown below:
[tex]M.M=4*12.01+11*1.01+5*14.01=129.164g/mol[/tex]
Secondly, we convert the mg of each tablet to grams and then divide the previously obtained molar mass to calculate the moles in a single tablet:
[tex]500.0mg*\frac{1g}{1000mg} *\frac{1mol}{129.164g} =0.003871mol[/tex]
Finally, we calculate the total number of moles she eats, assuming she gets three meals eaten in a single day and takes two per meal, which means there is a total of six tablets per day:
[tex]6*500.0mg*\frac{1g}{1000mg} *\frac{1mol}{129.164g}=0.02323mol[/tex]
