5) Mustard gas (C4H8Cl2S) was a gas used in WWI by Germany as a chemical warfare agent that when inhaled by enemy soldiers caused them to develop blisters on the exposed skin and lungs, sometimes resulting in death. A German chemist has a sample of mustard gas in a 1.25 L laboratory vessel. The temperature in the vessel is 22°C and the pressure is set to 5.00 atm. Calculate how many moles of mustard gas this chemist has in the vessel. Show all work and report your answer to the correct units and significant figures.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
