Answer: The partial pressure of oxygen in the mixture is 321 mm Hg

Explanation:

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

p_{total}=p_{He}+p_{N_2}+p_{O_2}

Given : p_{total} = total pressure of gases = 752 mm Hg

p_{He} = partial pressure of Helium = 234 mm Hg

p_{N_2} = partial pressure of nitrogen = 197 mm Hg

p_{O_2} = partial pressure of oxygen = ?

Putting in the values we get:

752mmHg=234mmHg+197mmHg+p_{O_2}

p_{O_2}=321mmHg

The partial pressure of oxygen in the mixture is 321 mm Hg
