The atomic number tells you how many protons are in an element.
Pressure<span> with Height: </span>pressure<span> decreases with</span>increasing altitude<span>. The </span>pressure<span> at any level in the atmosphere may be interpreted as the total weight of the </span>air<span> above a unit area at any </span>elevation<span>. At higher elevations, there are fewer </span>air<span> molecules above a given surface than a similar surface at lower levels.....</span>
<span>Sediments
Sediments are solid materials that were broken down by the process of erosion, weather and transported by the water, wind or glaciers and then deposited in a new location. Sediment can consist of minerals and rocks and can be as small as a grain of sand or as large as a boulder.</span>
<span>the process of eroding or being eroded by wind, water, or other natural agents. Hope this
helps.

Answer:
The partial pressure of helium gas in a gaseous mixture of helium and hydrogen is the pressure that the helium would exert in the absence of the hydrogen. equal to the total pressure divided by helium's molar mass. O equal to the total pressure divided by the number of helium atoms present.
