Answer
$C_{10}H_{20}N_{2}S_{4}$
Work Step by Step
Calculate the molar mass of the empirical formula by adding the molar masses of its constituent elements together.
$5(12.01)+10(1.01)+1(14.0)+2(32.07)= 148.29$
Divide the molar mass given by this number and round to the nearest whole number (it should be really close).
$\frac{296.54}{148.29}=2$
Multiply the Empirical formula by this number to get the molecular formula.
$2(C_{5}H_{10}NS_{2})=C_{10}H_{20}N_{2}S_{4}$
