Answer:
84.2mL
Step-by-step explanation:
The following data were obtained from the question:
Initial volume (V1) = 128mL
Initial pressure (P1) = 500mmHg
Final pressure (P2) = stp = 760mmHg
Final volume (V2) =..?
Thus, the new volume of the gas can be obtained by using the Boyle's law equation as follow:
P1V1 = P2V2
500 x 128 = 760 x V2
Divide both side by 760
V2 = (500 x 128)/760
V2 = 84.2mL
Therefore, the new volume of the gas is 84.2mL
