A mole is that number of molecular units of a substance. The number is called the Avogadro constant, or Avogadro's number. (It is defined as the no. of atoms in 12 grams of carbon-12).
For example, Iron has the chemical formula Fe. So a mole of iron is (Avogadro's no.) Fe atoms.
Water has the formula H2O. A mole of water, then, is (Avogadro's no.) H2O molecules.

How big does a mole typically grow in size?
A mole typically grows to be about 6 inches in length, including the tail.
What is inside a mole on the skin?
A mole on the skin is made up of clusters of pigment-producing cells called melanocytes. These cells give the mole its color and can sometimes grow in a raised or flat shape on the skin.
What are the potential risks associated with having hair on a mole, and should it be removed for health reasons?
Having hair on a mole can make it difficult to monitor changes in the mole's appearance, which could be a risk factor for skin cancer. It is recommended to consult a dermatologist to determine if the mole should be removed for health reasons.
How many molecules are in 1 mole of Glucose?
There are 6.022 x 10^23 molecules in 1 mole of glucose. This number is known as Avogadro's number and represents the number of units (atoms, molecules, etc.) in one mole of a substance.
Why is my mole growing hair?
The presence of hair on a mole is usually due to the mole being a type of skin growth called a nevus, which can contain hair follicles. This is a common occurrence and is typically not a cause for concern. However, if you notice any changes in the mole's size, shape, or color, it is important to consult a dermatologist to rule out any potential health risks.
How large is a mole in scientific notation?
6.022x10(to the 23rd power)
Is 1.11 mole more or less than 6.0221023 atoms?
One mole is approximately equal to Avogadro's Number of atoms, 6.023 times 10 to the 23rd power or 6.023E23, where "E" stands for "10 raised to the power of". So, 1.11 mole would be greater.
Where does the word mol come from in chemistry?
One "mole" of any element or compound is one "Avogadro's Number" of atoms or molecules; 6.023 times 10 to the 23rd power.
What is 6.0210 to the 23rd power molecules?
Avagadros number - The number of molecules/element that are found in one mole of the substance
What is 6.022 times 10 to the 23rd power?
6.022*10^23 is one mole of molecules this is typically used in Chemistry
How many atoms of gold in one mole of gold?
In one mole of gold, there are 6.022 x 10^23 atoms of gold. This number represents Avogadro's constant, which is the number of atoms, ions, or molecules in one mole of a substance.
What is mole determined by?
A mole, as in Chemistry, is merely a unit of measure. Saying there is a mole of something is similar to saying there is a dozen of something; it's not about size, it's about quantity. A mole uses Avagadro's number, which is roughly 6.02 x 10 to the 23rd power. that is, about 602000000000000000000000 atoms or molocules of an element is a mole of that element or compound. Another thing to note is that if you have a mole of water, for example, that means you have 2 moles of H and 1 mole of O, since there are 2 H's in water with 1 O.
How many CO2 moles comprise one mole of CO2?
6.02 ten to the power of 23
How many moles are in 1.204 x 1024 formula units of magnesium nitrate?
A mole is 6.023 x (ten to the 23rd power) formula units. (Avogadro's number). Thus you get your answer by dividing your number by Avogadro's number. As you have written your number, the answer would be 2.047 x (10 to the minus 21). However, as the wikianswers font won't let us do superscripts, I think you probably have 1.204 x (10 to the twenty fourth power), and that you are expected to use the approximation 6.02 x (ten to the 23rd power) for Avogadro, which gives a much simpler answer of 20.
What is the unit of mole in cgs unit?
In the CGS system, the unit of mole is the "mole" itself. The quantity of substance is still represented by Avogadro's number, which is approximately (6.022 \times 10^{23}) entities.
Can you give me an example of a mole fraction?
10 to the power of 7?
If you had a mole of MM's how many times could cover the surface of the earth?
7 times
