Answer:

#9.28 * 10^23# molecules of #C"Cl_4#

Explanation:

Using stoichiometry, we need to convert grams of #(C"Cl_4)# to moles, then moles to molecules.

#237color(red)cancel(color(black)("g")) * (1color(red)cancel(color(black)("mol")))/(153.82color(red)cancel(color(black)("g"))) * (6.02*10^23"molecules")/(1color(red)cancel(color(black)("mol"))) = 9.28 * 10^23"# #"molecules"#
