Answer: 22368.4 Liters
Step-by-step explanation:
Initial Volume of gas V1 = 20000 liters
Initial pressure of gas P1 = 850 torr
Final volume V2 = ?
Final (standard) pressure P2 = 760 torr
Apply the formula for Boyle's law:
P1V1 = P2V2
850torr x 20000L = 760torr x V2
V2 = (850torr x 20000L)/ 760torr
V2 = (17000000)/760torr
V2 = 22368.4L
Thus, the volume of the gas at standard pressure is 22368.4 Liters
