Answer: The partial pressure of neon in the mixture is 263 mm Hg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 815 mm Hg
= partial pressure of helium = 201 mm Hg
= partial pressure of nitrogen = 351 mm Hg
= partial pressure of Neon = ?
putting in the values we get:
The partial pressure of neon in the mixture is 263 mm Hg
