Question

If the barometric pressure (Patm) is 752 Torr and h = 123 mmHg, then what is the pressure of the gas in the bulb? Please express your answer in units of atmospheres.

Answer 1

Given:

The barometric pressure (Patm) is 752 Torr and h = 123 mmHg,

To find:

What is the pressure of the gas in the bulb? Please express your answer in units of atmospheres.

Solution:

From given, we have,

The barometric pressure (Patm) is 752 Torr and h = 123 mmHg.

Therefore, we have,

h = 123 mmHg

we have, 1 mmHg = 1 torr

∴ h = 123 torr

we use the formula,

Pgas = Patm

= 752 + 123

= 875 torr

we have 1 torr = 0.00131579 atm

∴  875 torr = 1.15132 atm

Therefore, the pressure of gas in atm is 1.15132 atm
