Question

What will be the partial pressure of $N _ { 2 }$ and 16 g of

• A. 1/2 the total pressure
• B. 1/3 the total pressure
• C. 1/4 the total pressure
• D. 1/16 the total pressure

Answer 1

Answer: (A)

1/2 the total pressure

Answer 2

$n \left( H _ { 2 } \right) = \frac { 2 } { 2 } = 1 , n \left( N _ { 2 } \right) = \frac { 14 } { 28 } = 0.5$,

$n \left( O _ { 2 } \right) = \frac { 16 } { 32 } = 0.5 , p \left( H _ { 2 } \right) = \frac { 1 } { 1 + 0.5 + 0.5 } p = \frac { 1 } { 2 } p$
