Question

What is 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?

Answer 1

Answer: The total pressure in atmospheres is 0.689

Step-by-step explanation:

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

`p_(total)=p_A+p_B+p_C...`

Given :
`p_(total)` =total pressure of gases = ?

`p_A` = partial pressure of A = 0.118 atm

`p_B` = partial pressure of B = 35.6 kPa = 0.351 atm (1kPa =0.0098atm)

`p_C` = partial pressure of C = 167 mm Hg = 0.220 atm (1mmHg=0.0013 atm)

putting in the values we get:

`p_(total)=0.118atm+0.351atm+0.220atm`

`p_(total)=0.689atm`

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
