The volume occupied by the Ammonia gas is C. 67.2 Liters. Ammonia is a compound that is composed of both nitrogen and hydrogen. Ammonia is normally used in order to rouse people into consciousness when they faint. Take note that Ammonia gas can be dangerous when it is inhaled in large amounts. It can also be problematic when it is consumed in liquid form.
This sometimes comes in liquid form too but it should not be mixed with certain compounds in any way. For example, when this becomes exposed to bleach, expect that a type of poisonous gas can be formed and this will be deadly for a lot of people. This should be handled carefully at all times.
The answer for this is letter C. 67.2 Liters. Take note that there are different factors that may affect the volume that is occupied. For example, if there is a different type of gas used, then it will occupy a different amount of space. The amount of gas that will be placed will also be one of the most important factors to consider.
Take note that STP stands for Standard Temperature and Pressure. This is the type of process that is usually followed when trying o get information about gases in general. Other processes are used when measuring the volume of liquids and solids.
