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

12 grams
Exactly 12 grams of pure carbon-12 powder is known as one mole.

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

Explanation: Carbon-14 is an isotope of carbon that has a relative atomic mass of 14. = 2.32⋅10−23g (3 s.f.)

What is the mass of carbon-14?

14 amu
Carbon-14 (14C): The carbon isotope whose nucleus contains six protons and eight neutrons. This gives an atomic mass of 14 amu. C is radioactive with a half-life of 5730 years (and so this isotope is sometimes called radiocarbon); because of this it is used in radiocarbon dating.

What is the mass of a carbon-12 atom?

12 amu
The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.

What is the mass of 1 mole of carbon *?

The mass of one mole of carbon-12 atoms is 12 grams. A mole is a set number of particles, whether that is atoms or molecules.

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 neutrons does carbon 12 have?

6 neutrons
Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes. The addition of even one neutron can dramatically change an isotope’s properties.

What is the atomic mass of carbon 13?

Carbon-13 (13C): The carbon isotope whose nucleus contains six protons and seven neutrons. This gives an atomic mass of 13 amu. six neutrons, resulting in an atomic mass of 12 amu.

What is the mass of carbon?

12.0107 u
Carbon/Atomic mass

How do you find the mass of carbon-12?

To find the average atomic mass, you take a certain number of atoms, find the total mass of each isotope, and then divide the total mass of all the atoms by the total number of atoms. Assume that you have, say, 10 000 atoms of carbon. Then you have 9893 atoms of 12C and 107 atoms of 13C .

What is the mass of six moles of carbon-12?

It means that NA (Avogadro’s number =6.022×1023) 12C atoms have a mass of 12.0⋅g . You have specified 6.0⋅g . Thus 6.0⋅g12.0⋅g⋅mol−1 = 0.50⋅mol .

What is the mass of 1.56 x10 21?

Mass of 1 Mg atom = 24.305 a. m. u. Mass of 1.56 × 10^21 Mg atoms = 1.56 × 10^21 × 24.305) a. m. u. = 1.56 × 10^21 × 24.305 × 1.6603 × 10^-24) g = 6.295 × 10^-2 g. Hope this helps.
