a tank contains helium gas at 490 mmHg, nitrogen gas at 0.75 atm, and neon at 520 torr. What is the total pressure in atm?
Dalton's Law says that the total pressure of a system is the sum of the individual partial pressures of any gas(es) present.
If you convert torr and mmHg to atm ( by dividing them by 760) and add all the atm together you get 2.07
To find the total pressure in atm, we need to convert all the given pressures to a common unit of measurement (atm) and then add them together.
Given:
Pressure of helium gas = 490 mmHg
Pressure of nitrogen gas = 0.75 atm
Pressure of neon gas = 520 torr
We know that:
1 atm = 760 mmHg
1 atm = 760 torr
So, let's convert the given pressures to atm:
Pressure of helium gas = 490 mmHg * (1 atm / 760 mmHg) = 0.6447 atm
Pressure of nitrogen gas = 0.75 atm (no conversion needed)
Pressure of neon gas = 520 torr * (1 atm / 760 torr) = 0.6842 atm
Now, we can add the pressures together to get the total pressure:
Total pressure = 0.6447 atm + 0.75 atm + 0.6842 atm = 2.0789 atm
Therefore, the total pressure in atm is approximately 2.08 atm.
To find the total pressure in atm, we need to convert the pressure of each gas to the same unit (atm) and then add them together.
Given:
Helium pressure = 490 mmHg
Nitrogen pressure = 0.75 atm
Neon pressure = 520 torr
First, convert the pressure of helium from mmHg to atm:
1 atm = 760 mmHg
So, helium pressure in atm = 490 mmHg / 760 mmHg/atm ≈ 0.645 atm
Next, convert the pressure of neon from torr to atm:
1 atm = 760 torr
So, neon pressure in atm = 520 torr / 760 torr/atm ≈ 0.684 atm
Now, add the pressures of all the gases together:
Total pressure in atm = Helium pressure + Nitrogen pressure + Neon pressure
Total pressure in atm ≈ 0.645 atm + 0.75 atm + 0.684 atm ≈ 2.079 atm
Therefore, the total pressure in the tank is approximately 2.079 atm.
