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. CH2.36N0.09O0.18P0.09S0.09  B. C11H26NO2PS  C. C22H52N2O4P2S2  D. C66H156N6O12P6S6  E. none of these are the correct empirical formula Feedback: Great! Empirical Formula discussed in Chapter 6.2. Question 2 of 25 4.0/ 4.0 Points `Batrachotoxin (C31H42N2O6) is the most potent non-peptide (we'll learn what that means in Lesson 7) based poison known. It gained fame though its use in poison darts made from frog excretions. The frogs themselves don't produce the toxin directly, but through digestion of Melyrid beetles the frogs eat. Suppose you are trekking through the rainforest and discover an even more potent toxin that has the same empirical formula as batrachotoxin. If the molar mass of this new poison is 3,232.02 g/mol, what is its molecular formula?  A. C31H42N2O6  B. C15.5H21NO3  C. C186H252N12O36  D. C1240H1680N80O240 Feedback: Great! Empirical Formula discussed in Chapter 6.2. Question 3 of 25 0.0/ 4.0 Points `Nicotine (C10H14N2), a member of the nightshade family of plants, is an oily liquid that makes up between 0.6 to 3% of a cigarette's mass. Contact with the liquid pure form can cause death within hours, as nicotine passes through the dermis and heads directly for the bloodstream. Overdoses and death can easily occur in those smoking cigarettes with nicotine patches applied on their body. How many nicotine molecules are in 1.00 g of nicotine?  A. 3.71 x 1021  B. 9.76 x 10
