# 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?

Approx. 5%.

#### Explanation:

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

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

These are incredibly corrosive and harmful reagents whose use is possibly still legal in warfare. That this was manufactured and deployed on monumental scales is incredibly morally bankrupt. Of course, which is more immoral? Making an explosive chemical to kill people, or making a chemical like this one that would maim and harass?
