First, we have to establish that the sum of the percentages is 100% of the sample. Now if we assume that we have a total of 100g of the sample, this means that the percentages of each element will just be the same value in grams.
From the mass, we can now divide by molar mass to get the moles:
A compound contains 47.08% carbon, 6.59% hydrogen, and 46.33% chlorine by mass; the molar mass of the compound is 153 g/mol. What are the empirical and molecular formulas of the compound?
