Suppose two gases in a container have a total pressure of 1.20 atm. What is the pressure of Gas B if the partial pressure of Gas A is 0.75 atm?

Respuesta :

Gas B= 0.45..... because all u need to do is subtract the total from the partial pressure of Gas A. Hope thats right and is able to help.

Answer: The partial pressure of Gas B is 0.45 atm.

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

[tex]p_{total}=p_A+p_B+p_C...[/tex]

Given : [tex]p_{total}[/tex] =total pressure of gases = 1.20 atm

[tex]p_A[/tex] = partial pressure of A =0.75 atm

[tex]p_B[/tex] = partial pressure of B =?atm

putting in the values we get:

[tex]1.20atm=0.75atm+p_B[/tex]

[tex]p_B=0.45atm[/tex]

The partial pressure of Gas B is 0.45 atm.
