What is the mass of 12 moles of carbon?

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 1023 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.
