1) The nerve gas Sarin, which was released in a Tokyo subway station in 1996, has a molecular formula of C4H10PO2F. You are a detective that has just isolated an unknown, "suspicious" compound in a raid. You are asked to determine if it is Sarin. To do so, you combust a 10.0g sample of this compound. In this reaction, some of the atoms in sarin will combine together with oxygen to make new molecules. 15.6g CO2 and 6.4g H2O are produced in this reaction, along with other products. Using numerical calculations, prove that this compound cannot be Sarin. Explain your reasoning clearly. (Problem developed by Logan M. McCarty)

Question
1) The nerve gas Sarin, which was released in a Tokyo subway station in 1996, has a molecular
formula of C4H10PO2F. You are a detective that has just isolated an unknown, “suspicious"
compound in a raid. You are asked to determine if it is Sarin. To do so, you combust a 10.0g
sample of this compound. In this reaction, some of the atoms in sarin will combine together with
oxygen to make new molecules. 15.6g CO2 and 6.4g H½O are produced in this reaction, along
with other products. Using numerical calculations, prove that this compound cannot be Sarin.
Explain your reasoning clearly. (Problem developed by Logan M. McCarty)
2) Estimate the number of water molecules on Earth. Work in powers of ten if possible, and do
