Question

An tank contains oxygen (O2) at a pressure of 2.29 atm . What is the pressure in the tank in terms of mmHg? What is the pressure in the tank in kPa?

Answer 1

Explanation:

We have to convert the tanks pressure from atm to mmHg. We know that 1 atm is equal to 760 mmHg. We can use this relationship to find the answer to our problem.

1 atm = 760 mmHg

P = 2.29 atm = 2.29 atm * 760 mmHg/(1 atm)

P = 1740 mmHg

Then 1 atm is equal to 101.325 kPa.

1 atm = 101.325 kPa

P = 2.29 atm = 2.29 atm * 101.325 kPa/(1 atm)

P = 232 kPa

Answer: The pressure is 1740 mmHg or 232 kPa.
