Citric acid (H3C6H5O7) is a product of the fermentation of sucrose (C12H22O11) in air.

C12H22O11(aq) + 3 O2(g) 2 H3C6H5O7(aq) + 3 H2O(l)


Determine the mass of citric acid produced when 3.20 mol C12H22O11 is used.

Citric acid has the molecular formula C6H8O7 so you can add the molar masses of the elements from the Periodic Table.

C has a molar mass of 12.01 g/mol, H has 1.01 g/mol and O has 15.999 g/mol.

Now you calculate the total molar mass= (6*12.01 + 8*1.01 + 7*15.999)

---

This yields a molar weight of 192.124 g/mol (anhydrous). When in solution as the monohydrate, this increases to 210.14 g/mol .
