Answer:

#0.33# #"mol C"_6"H"_12"O"_6#

Explanation:

We're asked to find the number of moles in #60# #"g"# glucose, #"C"_6"H"_12"O"_6#.

To do this, we can use the molar mass of glucose, calculated to be

#6(12.01color(white)(l)"g/mol") + 12(1.01color(white)(l)"g/mol") + 6(16.00color(white)(l)"g/mol")#

#= color(red)(180.18# #color(red)("g/mol"#

Using dimensional analysis, we can now convert from grams to moles:

#60cancel("g glucose")((1color(white)(l)"mol glucose")/(180.18cancel("g glucose"))) = color(blue)(0.33# #color(blue)("mol C"_6"H"_12"O"_6#
