This problem is providing the atmospheric pressure at 2000 m altitude which is 560. mmHg and asks for this pressure in units of atmospheres, which after doing the calculations, the result is 0.737atm.

<h3>Atmospheric pressure:</h3><h3 />

In this case, we can firstly define the concept of atmospheric pressure, also known as barometric pressure, as that pressure exerted by a column of air over a specific point in space at a defined altitude.

<h3>Units conversion in pressure:</h3><h3 />

In order to get the correct conversion, we use the following equivalence statement relating mercury millimeters and atmospheres:

760 mmHg = 1 atm

Hence, the required conversion turns out to be:

$560.mmHg*\frac{1atm}{760mmHg}=0.737atm$

k0ka [10]

K2CO3 can be thought to contain 6 atoms (2 K, 1 C, 3O).

If you are given grams of K2CO3 you can divide by the molar mass to get to moles and then multiply by Avogadro's number.
