Hello, Tran,
First, let's covert 6 lb to grams. There are 453.592 grams in 1 lb.
(6 lb)*(453.6g/lb) = 2721.6 grams sugar
Molar mass of C12H22O11 is 342.1 g/mole
Moles of C12H22O11 = 2721.6g/342.1 g/mole = 7.955 moles
(7.955 moles)*(6.022x1023 molecules/mole) = 4.79x1024 molecules sugar

You are welcome. Mole problems are easier than they look. Just rmember that a mole is nothing more than a unit, just like 1 foot is 12 inches. Except that 1 mole is equal to a Very Large Number, 6.022x10^23. The word "mole" can be used for anything: I have 1 mole of 1) paper clips, 2) friends, 3) dollars, 4) atoms, 5) molecules, 6) homework problems, etc.
