The amount of grams of hydrogen that are in the water sample is;
3.985 g
<h3>Avogadro's number</h3>
We are given that;
Number of moles of oxygen in a sample of water = 12 × 10²³
- Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.
Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles
Now, molar mass of hydrogen is 1 g/mol and we know that;
Molar mass = Avogadro's number(6.023 × 10²³) moles
Thus;
6.023 × 10²³ moles = 1 g/mol
Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)
⇒ 3.985 g

Explanation:
Encryption protects sensitive information is explanation best explains the importance of using encryption. Personal information and important information are protected, and communication between client apps and servers is made more secure.
<h3>What is Encryption?</h3>
Encryption is a way of securing digital data that employs one or more mathematical procedures, as well as a password or "key" to decrypt the information.
Data is encrypted using an algorithm that makes the original data unreadable. The name of two different data comes from the fact that encryption and decryption are done with the same key.
Thus option C is correct.
