The formula for mustard gas used in chemical warfare is #C_4H_8SCl_2#, which is 159.09 g/mol. What is the percentage of hydrogen in the compound?

Answer 1

Approx. #5%#.

#%H# #=# #"Mass of hydrogen"/"Mass of compound"xx100%# #=#

#(8xx1.00794*g*mol^-1)/(159.09*g*mol^-1)xx100%# #~=5%#.

The fact that this was produced and used on such a large scale is morally repugnant. These are extremely harmful and corrosive reagents, and it's possible that they can still be used lawfully in warfare. Which is more immoral, producing an explosive chemical that kills people or a chemical like this that would maim and harass people?
