Question

A sample of gas occupies 100.0 mL at standard pressure. What volume will the gas occupy at a pressure of 80.0 mm Hg if the temperature remains constant? *

Answer 1

950mL

Step-by-step explanation:

The following were Data were obtained from the question:

Initial volume (V1) = 100mL

Initial pressure (P1) = stp = 760mmHg

Final pressure (P2) = 80mmHg

Final volume (V2) =..?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P1V1 = P2V2

760 x 100 = 80 x V2

Divide both side by 80

V2 = (760 x 100) /80

V2 = 950mL

Therefore, the new volume of the gas is 950mL
