Mole has no dimensional formula. It is used to express the quantity of anything or material. 1mol=6.023 * 10^23 quantity of a substance(electrons, protons, apples, etc.) Mole is a fundamental unit.

## What is the dimensional formula for mole?

Dear Student , moles is a ratio of mass of a substance divided by the molecular mass of substance(in case substance is a compound)or divided by atomic mass(in case substance is an element) , So we can say that mole is a ratio of two masses. Hence a mole has no dimensional formula.

## What is the dimension of molar number?

## What is mole for dimensional analysis?

Chemists generally use the mole as the unit for the number of atoms or molecules of a material. 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).

## Why is a mole 6.022 x10 23?

The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×10^{23} elementary entities of the substance.

## What is the dimension of molar mass?

The dimension of molar mass is grams per mole (g/mol). For clarity the symbol mol should always be followed by the substance involved. For example: The molar mass of sodium is: 22.99 g/mol Na.

## Is number of moles dimensionless?

yes , mole is dimensionless quantity . e.g mole is the ratio of Same dimensional quantity . so , mole is dimensionless quantity.

## Does dimension have molarity?

In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol⋅dm^{−}^{3} in SI unit. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M.

## What is the dimension of weight?

The dimension of weight is MLT−2: mass times acceleration, that is, a force.

## What is the formula for dimensional analysis?

for some powers a, b, c, d, e, f, and g. We can write the dimensions of a length in this form with a = 1 and the remaining six powers all set equal to zero: L1=L1M0T0I0Θ0N0J0.

## What is a molecular mole?

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

## Why are there moles in my yard?

Moles are in your lawn because you have a food source in your soil; most likely grubs or earthworms. Moles burrow their way into our yards, creating raised tunnels on the surface and stacking up dirt when they make exit holes. They do this in search of food. … Moles need quite a bit of food to survive.

## Does Avogadro’s number have units?

Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10^{23}. The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any).

## How is 1 mole equal to 6.022 x1023 particles atoms molecules?

SI def.: the amount of a substance that contains the same number of entities as there are atoms in 12 g of carbon-12. Exactly 12 g of carbon-12 contains 6.022 x 1023 atoms. O molecules contains 6.022 x 1023 molecules. 1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1.

## What is the value of 1 amu?

1 amu = Average of the proton rest mass and the neutron rest mass. 1 amu = 1.67377 x 10 -27 kilogram or 1.67377 x 10 -24 gram.
