Work Step by Step

Calculate the molar mass of the empirical formula by adding the molar masses of its constituent elements together. $6(12.01)+7(1.01)+1(14.0)=93.13$ Divide the molar mass given by this number. $\frac{186.24}{93.13}=2$ Multiply the empirical formula by this number to get the molecular formula. $2(C_{6}H_{7}N)=C_{12}H_{14}N_{2}$
