## How much is a mole of carbon-12?

Exactly **12 grams** of pure carbon-12 powder is known as one mole. The number of atoms of carbon-12 present in this one mole sample is 6.022 136 7 x 10^{23}. This number is known as Avogadro’s number.

## Is 12g carbon one mole?

We have given that **one mole of carbon atom weighs 12 g**. A mole is defined as exactly equal to 6.022×1023 atoms. So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g.

## What is the 12 in carbon?

The 12 in carbon-12 is **the mass number of the isotope**. This means that all atoms of carbon-12 have a mass of 12 atomic mass units.

## What is a mole carbon-12?

Mole (mol): the amount of material counting 6.02214 × 1023 particles. The value of the mole is equal to **the number of atoms in exactly 12 grams of pure carbon-12**. • 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## Why is the mole based on carbon-12?

Carbon-12 is the basis for the mole **because the atomic mass of 12 grams of Carbon-12 is exactly the Avogadro’s number which defines a mole**.

## How many moles are there in 24g of carbon?

Answer: one mole of carbon contains 6.022 x 10^23 atoms mass of one mole of carbon= 12g. Therefoe, in 24 gra, **2 (2 x 12) moles** of carbon are there.

## What is the mass of carbon-12 in grams?

**1.992×10−23 gm**.

## Why carbon 12 is a standard reference?

Carbon-12 is **the standard while measuring the atomic masses**. Because no other nuclides other than carbon-12 have exactly whole-number masses in this scale.
