The H 2 produced in a chemical reaction is collected through water in a eudiometer. If the pressure in the eudiometer is 760.0 t
siniylev [52]

Answer:

the pressure (torr) of theH₂ gas is 736.2 torr

Explanation:

Given that

The H₂ gas  produced in a chemical reaction is collected through water in a eudiometer; during this process, the gas collected contains some droplets of water vapor along with these gas.

So; the total pressure in the eudiometer = Pressure in the H₂ gas  - Pressure of the water vapor

Where;

P_{Totsl} =  total pressure in the eudiometer = 760.0 torr

P_{H_2} = Pressure in the H₂ gas  = ???

P_{H_2O} = Pressure in the water vapor  = 23.8 torr

Now:

P_{Totsl} = P_{H_2} + P_{H_2O}

- P_{H_2} = + P_{H_2O} - P_{Totsl}

P_{H_2}  = - P_{H_2O} + P_{Totsl}

P_{H_2}  =  (- 23.8 + 760) torr

P_{H_2}  = 736.2 torr

Thus; the pressure (torr) of theH₂ gas is 736.2 torr
