Problem

For the next three questions consider a 10 L sample of gaseous chlorine atoms in their natural relative abundances (3:1 35Cl : 37Cl). The Cl atoms react to form Cl2 gas.

1. Which is the most likely mass spectrum of the products?

2. What volume (in L) does the gas occupy after the reaction of the Cl atoms to form Cl2?

3. Which is the mass spectrum if the Cl2 is split back into atoms?

Solution

For the first question, we’re being asked to determine the mass spectrum of the products when gaseous chlorine atoms with their natural abundances react to form Cl2 gas.

Mass Spectrometry allows you to determine the molecular weight of an unknown compound through its vaporization and ionization. 

Mass spectrometer is used to determine the mass to charge ratio of an unknown compound
