Three of the primary components of air are

Answer 1

Answer:

174.402 Torr is the partial pressure of oxygen gas.

Explanation:

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.

$P_T=p_{1}+p_{2}+p_{3}...p_{n}$

where,

$P_T$ = Total pressure

$p_{1}$ = partial pressure of gas-1

$p_{2}$ = partial pressure of gas-2

$p_{3}$ = partial pressure of gas-3

$p_{n}$ = partial pressure of nth gas in the mixture

We have:

$P_T= 1 atm = 760 Torr$

$p_{CO_2}=0.285 Torr$

$p_{N_2}=585.313 Torr$

$p_{O_2}=?$

Now put all the given values is expression, we get the partial pressure of the $O_2$ gas.

$P_T=p_{CO_2}+p_{N_2}+p_{O_2}$

$760 Torr=0.285 Torr+585.313 Torr+p_{O_2}$

$p_{O_2}=174.402 Torr$

174.402 Torr is the partial pressure of oxygen gas.
