Answer:
7.4 atm.
Explanation:
The total pressure of a mixture of gases is the summation of the partial pressure of the individual gases.
Ptotal = (P)He + (P)CO₂ + (P)N₂ = 4.1 atm + 0.6 atm + 2.7 atm = 7.4 atm.
Answer : The total pressure in the cylinder is 7.5 atm.
Solution :
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
[tex]P_T=p_{He}+p_{CO_2}+p_{N_2}[/tex]
where,
[tex]P_T[/tex] = total partial pressure in the cylinder = ?
[tex]P_{He}[/tex] = partial pressure of helium = 4.21 atm
[tex]P_{CO_2}[/tex] = partial pressure of carbon dioxide = 0.6 atm
[tex]P_{N_2}[/tex] = partial pressure of nitrogen = 2.7 atm
Now put all the given values is expression, we get:
[tex]P_T=4.21atm+0.6atm+2.7atm[/tex]
[tex]P_T=7.5atm[/tex]
Therefore, the total pressure in the cylinder is 7.5 atm.
