Question

Hydrogen is collected over water at 0.975 atm and 28°C. What is the partial pressure of H2?

Answer 1

Answer:

P ( dihydrogen ) = 0.938 atm

Explanation:

As we know that ,

P ( measured ) = P (svp)   +  P ( dihydrogen )

P ( dihydrogen ) = P ( measured ) - P (svp)  

Given data:

P ( svp ) = 28 mm Hg at Standard temperature.

P ( measured ) = 0.975 atm

Solution :

P ( dihydrogen ) = 0.975 - 28 / 760  

P ( dihydrogen ) = 0.938 atm
