Most isotopes of iodine have half lifes ranging typically between a few nanoseconds and a couple of hours. A handful of isotopes can be expected to last for roughly two weeks, and the only stable isotope of iodine is 127I. Assuming then that you mean stable iodine, the relevant numbers are isotope 127 and element number 53 in the Periodic Table meaning that stable iodine has 127 particles in the core of which 53 are protons. From this we can deduce that one atom of 127I has 127 - 53 = 74 neutrons.
I leave it as an exercise to calculate the number of neutrons found in three atoms of iodine.

What is the mass of 1.14x10 24 atoms of iodine?
Fairly heavy! 1.14 X 1024 atoms of iodine ( 1 mole I/6.022 X 1023)(126.9 grams/1 mole I) = 240 grams of iodine -------------------------------
How many atoms are in .534 mole of Ni?
3.22e23 atoms
How many atoms in 1 mole?
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
How many atoms are in one unit of potassium iodine?
Potassium iodide is two atoms, one of potassium and one of iodine.
How many moles of c are in 000831 moles of co2?
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
