Question

If three unreactive gases having partial pressures $P_{A}, P_{B}$ and $P_{C} ;$ and their moles are respectively $1$ mole, $2$ moles and $3$ moles, then their total pressure is

• A. $P = P _{ A }+ P _{ B }+ P _{ C }$
• B. $P=\frac{\sqrt{P_{A}+P_{B}+P_{B}}}{3}$
• C. $P=\frac{P_{A}+P_{B}+P_{C}}{6}$
• D. none of these

Answer 1

Answer: (A)

If three unreactive gases having partial pressure $P _{ A ,} P _{ B }$ and $P _{ C }$ then the total pressure is represented as $P = P _{ A }+ P _{ B }+ P _{ C }$
