Explanation:
Hello,
Considering the ideal equation of state:
The moles are defined in terms of mass as follows:
Whereas the gas' molar mass, thus:
Now, since the density is defined as the quotient between the mass and the volume, we get:
Solving for :
Thus, the result is given by:
Best regards.
<h2>The new volume of the balloon at the top of Pikes Peak is 10.2 L</h2>
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 577.0 torr
= final pressure of gas = 400 torr
= initial volume of gas = 7.4 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Thus the new volume of the balloon at the top of Pikes Peak is 10.2 L

It is important to use chemicals of high quality and correct concentrations in experiment so that we can obtain the predictable result in an experiment
Purity of substances/chemicals is very important when performing experiments in the laboratories, because it plays an important role in the determination of the chemical properties of substances which will have a direct effect on the result obtained from the experiment. likewise using the correct concentration of reagents
During experiments to obtain the best/predictable result in an experiment it is of best practice to make use of chemicals of high quality and also at the exact(needed) concentrations, that way the predictable result of the experiment will be obtained.
