Answer:
The volume at 475 mmHg is 4.448 L
Explanation:
Step 1: Data given
Volume = 2.78 * 10³ mL = 2.78 L
Temperature = 25.0 °C
Pressure = 760 mmHg = 1 atm
The temperature stays the same
The pressure lowers to 475 mmHg = 475/760 = 0.625 atm
Step 2: Calculate the new volume
P1V1 = P2V2
⇒ with P1 = the initial pressure = 1 atm
⇒ with V1 = the initial volume = 2.78 L
⇒ with P2 = the final pressure = 0.625 atm
⇒ with V2 = the final volume = TO BE DETERMINED
V2 = 4.448 L
The volume at 475 mmHg is 4.448 L
