Consider #alpha#-glucose,

puu.sh

#C_6H_12O_6#

For now, you'll only have to worry about the chemical formula!

Moreover, recall Avogadro's number, which nearly every science major has memorized: #6.02*10^23#

Hence,

#523"g" * (C_6H_12O_6)/(180"g") * (6.02*10^23"molecules")/"mol" approx 1.75*10^24#

molecules of glucose are in your given mass.
