<u>Answer:</u> The molality of 
solution is 4.013 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg.
The formula used to calculate molarity:
.....(1)
Given values:
Given mass of = 20.0 g
Molar mass of = 62.3 g/mol
Mass of solvent = 80.0 g
Putting values in equation 1, we get:
Hence, the molality of solution is 4.013 m
Answer:
Pressure
Explanation:
The variable that describes how often the particles in a sample of gas collides with each other and the walls of the container is the pressure.
The pressure of a gas is the combined force with which the gas molecules bombard a unit area of the wall of the container i.e the sum of all the tiny pushes on the unit area of the wall of the container.
The various units of gas pressure atmosphere, millimeters of Hg, torr, pascal, newton per meter squared.
- Temperature is the degree of hotness or coldness of a body
- Volume is the space the gases occupies.
