A tank contains helium gas at 490 mm Hg, nitrogen gas at 0.75 atm, and neon at 520 torr. What is the total pressure in atm?

Answer 1

Approx. 2 atmospheres.

The gases were quoted with unrealistically different units; the total pressure is the sum of the individual partial pressures of each gas.

#1# #"atmosphere = 760 mm Hg = 760 Torr"#. You must convert the partial pressures to common units, and simply add them up.

And thus.

#P_"Total"=P_(He)+P_(N_2)+P_(Ne)#, and we can convert all the units to atmospheres......
#P_"He"=(490*"Torr")/(760*"Torr"*atm^-1)=0.645*atm#.
#P_(N_2)=0.75*atm#.
#P_"Ne"=(520*"Torr")/(760*"Torr"*atm^-1)=0.684*atm#.
#P_"Total"={0.645+0.75+0.684}*atm=2.08*atm#.

Answer 2

To find the total pressure, we need to convert all the pressures to the same units and then sum them up.

1 atm = 760 mm Hg = 760 torr

Pressure of helium gas = 490 mm Hg Pressure of nitrogen gas = 0.75 atm Pressure of neon gas = 520 torr

Now, let's convert the pressure of helium gas and neon gas to atm:

Pressure of helium gas = 490 mm Hg * (1 atm / 760 mm Hg) = 0.645 atm Pressure of neon gas = 520 torr * (1 atm / 760 torr) = 0.684 atm

Now, we sum up all the pressures:

Total pressure = Pressure of helium + Pressure of nitrogen + Pressure of neon Total pressure = 0.645 atm + 0.75 atm + 0.684 atm = 2.079 atm

Therefore, the total pressure in atm is approximately 2.079 atm.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
