Stoichiometric mole to mass conversion

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

C12H22O11 (aq) + 3O2 (g) --> 2H3C6H5O7 (aq) + 3H2O (I)

Determine the mass of citric acid produced when 2.50 mol C12H22O11 is used.

2.5mol curricular acid x 2 moles citric acid = 5 mols citric acid.

5 mols citric acid =

H3 = 3 x 1
C6 = 12 x 6
H5 = 5 x 1
O7 = 16 x 7
= 3 + 72 + 5 + 112
= 192g Citric Acid
