What is the % of water in FeSO4. 2H20​

Answer 1

Question:

→What is the % of water in FeSO4. 2H20

Answer:

• 58 grams FeSO4/(151.95 g/mole FeSO4) = 0.382 moles FeSO4. The molar mass of H2O is 18 g/mole H2O. That means the 40 grams of water represents: 40 g H2O/18 g/mole H2O = 2.222 moles of H2O.

Explanation:

→water is H2O. The atomic number of oxygen is 8, which means that it has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 4 electrons in the 2p orbital, in accordance with the Periodic Table of the Elements in Figure C-7.6.
