At constant temperature, if the pressure of the sample of the krypton gas increases to the given value, the volume decreases to 15mL.
Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
PāVā = PāVā
Where Pā is Initial Pressure, Vā is Initial volume, Pā is Final Pressure and Vā is Final volume.
Given the data in the question question;
Now, we substitute our given values into the expression above to determine the new volume of the krypton gas.
PāVā = PāVā
Vā = PāVā / Pā
Vā = 0.40atm Ć 0.075L / 2.00atm
Vā = 0.03Latm / 2.00atm
Vā = 0.015L
Vā = 15mL
Therefore, at constant temperature, if the pressure of the sample of the krypton gas increases to the given value, the volume decreases to 15mL.
