Verified step by step guidance1
Understand that pressure is defined as force applied per unit area. Therefore, units of pressure must reflect this relationship.
Recognize that 'kg' (kilogram) is a unit of mass, not pressure.
Know that 'mol' (mole) is a unit used to count the number of particles or amount of substance, not pressure.
Identify that 'L' (liter) is a unit of volume, which is not used to measure pressure.
Recall that 'atm' (atmosphere) is a common unit of pressure, representing the pressure exerted by the Earth's atmosphere at sea level.
