Moles of sucrose = 0.292 mol

Now, we are able to use Avogadro’s quantity to search out the variety of molecules:

Variety of molecules = Variety of moles x Avogadro’s quantity
Variety of molecules = 0.292 mol x 6.022 x 10^23 particles/mol
Variety of molecules = 1.76 x 10^23 particles

Which means the jar of sugar incorporates roughly 1.76 x 10^23 molecules of sucrose.
