Answer :
Answer:760 torr
Explanation:To convert the pressure from atmospheres (atm) to torr, we can use the conversion factor:
1 atm = 760 torr
So, we can multiply the pressure in atm by this conversion factor to get the pressure in torr:
5.58 atm × 760 torr/atm = 4248 torr
Therefore, the pressure of helium in the cylinder is approximately 4248 torr.
Note: The actual conversion factor is 1 atm = 759.95 torr, but 760 torr/atm is a commonly accepted approximation.
