## How many particles are there in one mole of potassium iodide?

The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to **6.02214179×1023 atoms**, or other elementary units such as molecules.

## How many moles are in KCl?

**One mol of KCl** is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.

## How many moles are in 166 grams of KI?

First, lets find the molar mass of KI: 39.1 g (K) + 126.9 g (I) = 166.0 g KI. Now we want to find the amount of K in KI, which can be solved by calculating K molar mass / KI molar mass, which means 39.1 g K / 166.0 g KI. We get 23.55%. In **one mole** or 166 g of KI, 23.55% of it is K.

## Is Ki ionic or covalent?

Correct answer:

Potassium iodide (KI) **forms an ionic bond**. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).

## What is the composition of K in KI?

**Potassium iodide** has the chemical formula KI. Commercially it is made by mixing potassium hydroxide with iodine.

## How many molecules are in 1 mole of molecules?

One mole (abbreviated mol) is equal to **6.022×10 ^{23} molecular entities** (Avogadro’s number), and each element has a different molar mass depending on the weight of 6.022×10

^{23}of its atoms (1 mole).

## What is the numerical value of mole?

One mole of a substance is equal to **6.022 × 10²³ units** of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant.
