Mole concept

One can of Welch's grape soda contains 0.283 moles of fructose (C6H1206). How many grams

of fructose are in one can of this soda?

Answer: 50.9g of Fructose

Explanation:

No of moles = Mass (g) / Molar Mass (g/mol)

Moles = 0.283

Molar Mass of Fructose (C6H12O6) = 12 x 6 + 1 x 12 + 16 x 6 = 180g/mol

Mass = ?

Make 'Mass' the subject of formular, we will have;

Mass = Molar Mass x No of moles

= 180g/mol x 0.283

= 50.9g of Fructose
