How many carbon(C) atoms are present in 30. mol of carbon?
1.8*10^25
All of these are alike. Refer to your post above.
To find the number of carbon atoms in a given amount of substance, you can use Avogadro's number and the concept of moles. Avogadro's number (represented by the symbol N_A) is approximately 6.022 x 10^23 mol^-1. It represents the number of atoms, molecules, or ions in one mole of a substance.
In this case, we have 30 mol of carbon. To determine the number of carbon atoms, we can multiply the number of moles by Avogadro's number:
Number of atoms = Number of moles × Avogadro's number
Substituting the given values:
Number of atoms = 30 mol × 6.022 x 10^23 mol^-1
Solving this equation:
Number of atoms = 1.8066 x 10^25
Therefore, there are approximately 1.8 x 10^25 carbon atoms present in 30 mol of carbon.
