Answer and Explanation:
Bernoulli's Principle deals with Fluid dynamics and fluid includes both liquid and gas.
The Principle gives an inverse relation between the speed or velocity of the fluid and the pressure of the fluid. It gives the speed or velocity of the liquid over varying pressure.
Bernoulli's Principle states that for a given fluid,the low pressure region will have high speed or velocity and high pressure region will have low speed or velocity
This problem provides information about the pressure and temperature ideal gases are studied at. The answer to the questions are that all molecules have the same density, 2.43x10²⁵ mol/m³ and 2.43x10¹⁹ mol/cm³.
<h3>Idela gases</h3>
In science, we can start studying gases with the concept of ideal gas, as they do not collide one to another and are assumed to be perfect spheres with no relevant interactions.
In such a way, one can conclude that the <u>number density of all ideal gasses at SATP is the same</u>, as they are assumed to be perfect spheres with equal volumes per molecule.
Moreover, when calculating the number of molecules per cubic meter, one must use the ideal gas equation as:

And plug in the numbers we are given:

Lastly, we can calculate the molecules per cubic centimeter by performing the following conversion:

Mass and volume
Answer is C. when protons are equal to electrons their charges cancel out making it neutral because electrons have a charge of negative one and when you combine them positive 1 and negative 1 is 0.
