How many atoms are there in 1g of 14c
WebFor every mole, there are 6.02*10 23 atoms, so in 1 gram of hydrogen there are 6.02*10 23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms. Answer 3: Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unit is TINY. WebTo convert grams to a number of atoms, divide by the atomic mass of carbon-14 and multiply by Avagadro's number, 6.02 x 10 23. number of carbon-14 atoms : [10 grams x (1.2 x 10 -12) / (14 grams/mole)] x (6.02 x …

Carbon-14 is produced in the upper troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms. When cosmic rays enter the atmosphere, they undergo various transformations, including the production of neutrons. The resulting neutrons (n) participate in the following n-p reaction (p is proton): 7N + n → 6C + p Carbon-14 is produced in the upper troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms.
