Answer:

<u><em>H⁺</em></u>

Explanation:

There are three definitions of acids: Arrhenius, Bronsted - Lowry, and Lewis.

An Arrhenius acid is a substance that when dissolved in water will release a proton (H⁺ or hdyronoum, H₃O⁺) in solution.

The definition of Bronsted-Lowry is not limited to aqueous solution: an acid is a substance that releases protons in any solvent. So it includes, the Arrhenius acids but also other acids.

The Lewis Acid definition is wider. It includes both Arrhenius and Bronsted-Lowry acids and other substances that do not release protons. A Lewis acid is a substance that accepts an electron pair.

Thus, <em>when an acid is dissolved in a solution, following Bronsted-Lowry definition, </em><u><em>H⁺ ions are formed.</em></u>

How many moles are in 9.25E24 formulas units of sodium acetate?

Lelu [443]

Answer:

<h2>15.37 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{9.25 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.365448...$

We have the final answer as

<h3>15.37 moles</h3>
