You Create a Process to Be Used in Conjunction with Combustion

You create a process to be used in conjunction with combustion analysis using chlorine gas to determine the amount of selenium in certain organic compounds.If there is selenium in the molecule,SeCl₂ (149.87 g/mol) is produced.Analysis of 28.20 grams of an unknown compound produces 36.21 g CO₂,18.53 g H₂O,and 30.83 g SeCl₂.The molar mass of the compound is about 137 g/mol.What is its molecular formula?

A) C₄H₁₀Se
B) C₈H₂Se
C) C₉H₁₈Se
D) C₃H₁₂Se
E) C₂H₈Se
