Answer:

There are 2 moles of #"C"_6"H"_12"O"_6"# in 300 g #"C"_6"H"_12"O"_6"#, rounded to one significant figure.

Explanation:

First determine the molar mass (mass of one mole) of glucose, which is #"180.15588 g/mol"#. http://pubchem.ncbi.nlm.nih.gov/compound/5793

Next divide the given mass of glucose by its molar mass.

#300"g C"_6"H"_12"O"_6xx(1"mol C"_6"H"_12"O"_6)/(180.15588"g C"_6"H"_12"O"_6)="2 mol C"_6"H"_12"O"_6"# (#1.7# rounded to one significant figure)
