Explanation:
Hello,
In this case, since the both gases behave ideally, with the given information we can compute the moles of He in A:

Thus, since the final pressure is 3.60 bar, we can write:

The moles of helium could be computed via solver as:

Or algebraically:

In such a way, the volume of the compartment B is:

Finally, he mole fraction of He is:

Answer:
There have been seven horizontal rows of elements are called phases in the periodic table of elements. Groups, or families, are called vertical columns of elements. Metals, – anti, and metals are the most common ways of classifying the periodic table.

Answer:</h3>
1082.96 L
<h3>
Explanation:</h3>
We are given;
- Initial volume of helium gas, V1 = 793 L
- Initial temperature, T1 = 16.9°C
But, K = °C + 273.15
- Thus, initial temperature, T1 is 290.05 K
- Initial pressure, P1 = 759 mmHg
- New pressure at 4.05 km, P2 = 537 mmHg
- New temperature at 4.05 km, T2 = 7.1 °C
= 280.25 K
Assuming we are required to calculate the new volume at the height of 4.05 km
We are going to use the combined gas law.
- According to the combined gas law;




Therefore, the new volume of the balloon at the height of 4.05 km is 1082.96 L
