Total charge of electrons in 1.77 Kg of H20

In summary, the total charge of electrons in 1.77 Kg of H20 is zero, as H20 is a neutral molecule with an equal number of protons and electrons. There are approximately 1.03 x 10^26 electrons present in 1.77 Kg of H20, and this number is not affected by temperature or pressure. While the total charge of electrons does not directly affect the chemical properties of H20, it can influence its reactivity and bonding behavior. The total charge of electrons in 1.77 Kg of H20 can be altered by adding or removing electrons through chemical reactions or external factors.

Homework Statement


What is the total charge of all the electrons in 1.77 Kg of H20?


Homework Equations


I really just lost on how to do this problem as I missed school today. Any help would be greatly appreciated


The Attempt at a Solution



the 1st step I took was trying to find the total number of electrons and got 1.943E30 but this is probably wrong.

How many moles of H2O are there in 1.77 kg ?

(What is the molar mass of H2O)
 

1. What is the total charge of electrons in 1.77 Kg of H20?

The total charge of electrons in 1.77 Kg of H20 is zero. This is because H20 is a neutral molecule, meaning it has an equal number of protons and electrons. Therefore, the positive charge of the protons balances out the negative charge of the electrons, resulting in a net charge of zero.

2. How many electrons are present in 1.77 Kg of H20?

There are approximately 1.03 x 10^26 electrons present in 1.77 Kg of H20. This is based on the molar mass of H20 (18.02 g/mol) and Avogadro's number (6.02 x 10^23 particles/mol).

3. Is the total charge of electrons in 1.77 Kg of H20 affected by temperature or pressure?

No, the total charge of electrons in 1.77 Kg of H20 is not affected by temperature or pressure. As mentioned before, H20 is a neutral molecule and the number of electrons remains constant regardless of external factors.

4. How does the total charge of electrons in 1.77 Kg of H20 affect its chemical properties?

The total charge of electrons in 1.77 Kg of H20 does not directly affect its chemical properties. However, the arrangement of electrons in the molecule can influence its reactivity and bonding behavior with other molecules.

5. Can the total charge of electrons in 1.77 Kg of H20 be altered?

Yes, the total charge of electrons in 1.77 Kg of H20 can be altered by adding or removing electrons from the molecule. This can be achieved through chemical reactions or external factors such as ionizing radiation.
