Both evaporation and condensation are in the water cycle. evaporation is when water changes from liquid to gas meanwhile condensation is when water vapor cools and goes from gas to liquid.
The empirical formula of this compound is ![H_2SO_4](https://tex.z-dn.net/?f=H_2SO_4)
<u>Given the following data:</u>
<u>Scientific data:</u>
- Molar mass of hydrogen (H) = 1.0 g/mol.
- Molar mass of sulfur (S) = 32 g/mol.
- Molar mass of oxygen (O) = 16 g/mol.
To determine the empirical formula of this compound:
Note: We would assume that the mass of the compound is 100 grams.
Hence, the mass of its constituent elements are:
- Mass of hydrogen (H) = 2.00 grams
- Mass of sulfur (S) = 32.7 grams
- Mass of oxygen (O) = 65.3 grams
Next, we would determine the number of moles of each element by using this formula:
![Number\;of\;moles = \frac{mass}{molar\;mass}](https://tex.z-dn.net/?f=Number%5C%3Bof%5C%3Bmoles%20%3D%20%5Cfrac%7Bmass%7D%7Bmolar%5C%3Bmass%7D)
<u>For </u><u>hydrogen</u><u> (</u><u>H</u><u>):</u>
![Number\;of\;moles = \frac{2.00}{1}](https://tex.z-dn.net/?f=Number%5C%3Bof%5C%3Bmoles%20%3D%20%5Cfrac%7B2.00%7D%7B1%7D)
Number of moles = 2.0 moles
<u>For </u><u>sulfur</u><u> (</u><u>S</u><u>):</u>
![Number\;of\;moles = \frac{32.7}{32}](https://tex.z-dn.net/?f=Number%5C%3Bof%5C%3Bmoles%20%3D%20%5Cfrac%7B32.7%7D%7B32%7D)
Number of moles = 1.0 moles
<u>For </u><u>oxygen</u><u> (</u><u>O</u><u>):</u>
![Number\;of\;moles = \frac{65.3}{16}](https://tex.z-dn.net/?f=Number%5C%3Bof%5C%3Bmoles%20%3D%20%5Cfrac%7B65.3%7D%7B16%7D)
Number of moles = 4.0 moles
Empirical formula = ![H_2SO_4](https://tex.z-dn.net/?f=H_2SO_4)

Answer:
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.
Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
