The question is not found here but the results of a lab experiment can be used to draw discussions and conclusions.

<h3>What is an experimental procedure?</h3>

An experimental procedure in the lab refers to the process to validate (or reject) our working hypothesis from a given question of the natural world.

Within the laboratory, we need to collect data through experimental procedures that help us as evidence to answer the hypothesis.

In conclusion, the question is not found but the results of a lab experiment can be used to draw discussions and conclusions.

In a mixture of hydrogen and nitrogen gases, the mole fraction of nitrogen is 0.333. If the partial pressure of hydrogen in the
notka56 [123]

Answer:

P_T=112.4torr

Explanation:

Hello there!

In this case, since these problems about gas mixtures are based off Dalton's law in terms of mole fraction, partial pressure and total pressure, we can write the following for hydrogen, we are given its partial pressure:

P_{H_2}=x_{H_2}*P_T

And can be solved for the total pressure as follows:

P_T=\frac{P_{H_2}}{x_{H_2}}

However, we first calculate the mole fraction of hydrogen by subtracting that of nitrogen to 1 due to:

x_{H_2}+x_{N_2}=1\\\\x_{H_2}=1-0.333=0.667

Then, we can plug in to obtain the total pressure:

P_T=\frac{75.0torr}{0.667}\\\\P_T=112.4torr

Regards!
