Question

A tank contains a mixture of helium, argon and neon gases, with the following pressures 6.1 atm, 464 mmHg, 7.69 psi. What is the total pressure in the tank (in atmospheres)?

Answer 1

Answer: 7.24 atm

Explanation: To find the total pressure in the tank, we need to convert all of the pressures to the same unit. Let's convert the pressures to atmospheres (atm), since that is the unit requested in the question:

6.1 atm (given)

464 mmHg = 0.611 atm (since 1 atm = 760 mmHg)

7.69 psi = 0.529 atm (since 1 atm = 14.7 psi)

Now, we can add the pressures to find the total pressure in the tank:

Total pressure = 6.1 atm + 0.611 atm + 0.529 atm = 7.24 atm (rounded to two significant figures)

Therefore, the total pressure in the tank is 7.24 atm.
