A 275-mL flask contains pure helium at a pressure of 752 torr. A second flask with a volume of 475 mL contains pure argon at a p

hichkok12 [17]

Answer:

Partial pressure He = 276 torr

Partial pressure Ar = 457 torr

Total pressure = 733 torr

Explanation:

Assuming temperature remains constant, we can use Boyle's law to solve this problem: P₁V₁=P₂V₂.

Once the two flasks are connected and the stopock opened, the total volume is:

275 + 475 = 750 mL

Now we use Boyle's law twice, to calculate the new pressure of each gas:

He ⇒ 752 torr * 275 mL = P₂He * 750 mL

P₂He = 276 torr

Ar ⇒ 722 torr * 475 mL = P₂Ar * 750 mL

P₂Ar = 457 torr

Finally we calculate the total pressure, adding the partial pressures:

Total pressure = P₂He + P₂Ar = 733 torr
