Find the amount of water containing 14.02 * 10²⁴ molecules

14.02 x 10²⁴ molecules

Explanation:

To solve this problem we will use Avogadro's number: It relates to the number of molecules (or atoms) contained in 1 mol of any given substance:

14.02 x 10²⁴ molecules ÷ 6.023 x 10²³ molecules/mol = 23.28 moles

Thus, 23.28 moles of water contain 14.02 x 10²⁴ molecules.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
