Answer: The total pressure in atmospheres is 0.689
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 = ?
[tex]p_A[/tex] = partial pressure of A = 0.118 atm
[tex]p_B[/tex] = partial pressure of B = 35.6 kPa = 0.351 atm (1kPa =0.0098atm)
[tex]p_C[/tex] = partial pressure of C = 167 mm Hg = 0.220 atm (1mmHg=0.0013 atm)
putting in the values we get:
[tex]p_{total}=0.118atm+0.351atm+0.220atm[/tex]
[tex]p_{total}=0.689atm[/tex]
Thus the total pressure in atmospheres of a mixture of three gases with partial pressures of 0.118 atm, 35.6 kPa, and 167 mm Hg is 0.689 atm
