Answer:
340.8mL
Explanation:
The following data were obtained from the question:
P1 = 740.0mmHg
V1 = 350.0mL
P2 = at stp = 760mmHg
V2 =?
Using Boyle's law equation P1V1 = P2V2, we can easily find the new volume as illustrated below:
P1V1 = P2V2
740 x 350 = 760 x V2
Divide both side by 760
V2 = (740 x 350) /760
V2 = 340.8mL
The new volume is 340.8mL
