## How do you find the mass of a mole of carbon?

The mass of mole of carbon is it’s **molar mass times the number of moles**: (1 mole C)*(12.01 g/mole C) = 12.01 grams (the moles cancel, leaving grams). 12.01 grams of carbon supplies 6.02 x 10^{23} atoms of carbon.

## 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.

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

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).

## How do you find the mass of carbon-12?

The atomic mass of carbon would be **12.01 grams per mole of carbon atoms**. To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons.

## 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 is carbon-12 formed?

The answer comes in the form of **a reaction involving three helium nuclei**, also known as alpha particles. … At low temperatures, when the energy is not enough to reach the resonances, carbon-12 can still be formed through the simultaneous fusion of three alpha particles.

## What is the mass of a mole of carbon-12 a mole of carbon 14?

1 mole of C-14 has 6.023 × 10^23 atoms Therefore, the mass of 1 atom of C-14 is : 14/ 6.023×10^23 = 2.32 × 10^-23 g It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, **1.992646547 × 10 −23 gram**, which is assigned an atomic mass of 12 units. Caffeine has a molecular weight of 194.
