Question

One of the first chemical WMDs, researchers initially produced VX nerve agent for retail sale in the 1950s as a pesticide. Thankfully, your likelihood of coming in contact with VX is extremely low - the world's stockpiles have been destroyed, including the United States' main stockpile in Anniston, AL. The molecular formula for this nerve agent is C₁₁H₂₆NO₂PS, and it has a molar mass of 267.37 g/mol. Given this information, what is its empirical formula?

 A.CH_2.36N_0.09O_0.18P_0.09S_0.09 B.C₁₁H₂₆NO₂PS C.C₂₂H₅₂N₂O₄P₂S₂ D.C₆₆H₁₅₆N₆O₁₂P₆S₆ E.none of these are the correct empirical formula
