Chemical Formulas: Percent Composition
1.
The nerve gas Sarin, which was released in a Tokyo subway station in 1996, has a
molecular formula of C4H10PO2F.
Determine the composition (percent by mass) of each element in Sarin.
b)
An unknown compound is discovered in a raid on a terrorist organization; it is believed
that the compound is Sarin. When a 10.0-gram sample of this compound is completely
combusted, 15.6 g CO2 and 6.4 g H20 are produced, along with other combustion
products. Using numerical calculations, prove that this unknown compound can not be
Sarin.
A pulverized rock sample believed to be pure calcium carbonate is subjected to chemical
analysis and found to contain 51.3% calcium, 7.7% carbon, and 41.0% oxygen by mass.
Demonstrate that this natural sample cannot be pure CaCO3.
