How many iron atoms contained in a 0.83 mole sample of iron

5.00 x 10^23 atoms

Explanation:

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 atoms

So, 1 mole of Iron = 6.02 x 10^23 atoms

0.83 moles of Iron = Z atoms

To get the value of Z, cross multiply:

Z atoms x 1mole = (6.02 x 10^23 x 0.83)

Z = 5.00 x 10^23 atoms

Thus, there are 5.00 x 10^23 atoms of iron.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

did anyone actually do this? like if anyone has submitted this i rly need .
