Work Step by Step

Calculate the molar mass of the empirical formula by adding the molar masses of its constituent elements together. $1(12.01)+1(35.45)= 47.46$ Divide the molar mass given by this number and round to the nearest whole number (it should be really close). $\frac{284.77}{47.46}=6$ Multiply the Empirical formula by this number to get the molecular formula. $6(CCl)=C_{6}Cl_{6}$
