Answer: a) 525 ml
b) 67.2 ml
Step-by-step explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
a)
= initial pressure of gas = 752 mm Hg
= final pressure of gas = 385 mm Hg
= initial volume of gas = 250 ml
= final volume of gas = ?
Therefore, the volume at 385 mm Hg is 525 ml.
b)
= initial pressure of gas = 752 mm Hg
= final pressure of gas = 3.68 atm = 2796.8 mm Hg (760mmHg=1atm)
= initial volume of gas = 250 ml
= final volume of gas = ?
Therefore, the volume at 3.68 atm is 67.2 ml.
