Xenon gas measure pd to start sith s volume of 15.5kL. If the the volume changes to the 0?6kL and the pressure becomes 44 Pa, what was the original pressure? Read carefully!

17.03Pa

Explanation:

Given parameters:

Initial volume  = 15.5kL

Final volume  = 6kL

Final pressure  = 44Pa

Unknown:

Original pressure = ?

Solution:

The parameters given shows pressure and volume relationship of the given gas. One of the gas laws that predicts pressure - volume relationships is the Boyle's law.

Boyle's law states that "the volume of a fixed mass of gas varies inversely as the pressure changes, if the temperature is constant".

Mathematically,  

             P₁V₁   = P₂V₂

where P₁ is the initial pressure

           V₁ is the initial volume

           P₂ is the final pressure

           V₂ is the final volume

Input the variables and solve for P₁;

               P₁ x 15.5  = 44 x 6

                      P₁  = 17.03Pa

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
