Since a molecule of krypton is a single atom, the answer to this question is the quotient of 1.3 X 1016 divided by Avogadro's Number, or about 2.2 X 10-8 mole.
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
each mole has avogadro's number of atoms in it, which is 6.02 x 10 to the 23rd power. so, 4 x 6.02 x 10 23 power of atoms
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
6.55 * 1024 atoms = ? moles of carbonTake the number of atoms and divide it by Avogrodos constant (6.02 * 1023). Note that if you are looking to have your units cancel, multiply the number of atoms times 1 mole and divided by atomic mass. But if you know why it is just multiplied by one, there is no reason to put it in the formula.6.55 * 1024 atoms / (6.02 * 1023) = 10.9 molescarbon
2 (atoms N / molecule N2) * 8.5*10+24 (molecules N2) / 6.02*10+23 (atoms N / mole N-atoms) = 28 mole N-atoms
One mol of copper is 6.02 x1023 atoms. So 3.44 x 1023 would be 0.571 moles.
5.22 x 10 to the power of 22 iron atoms is equivalent to 0,087 moles.
1 mole Kr = 6.022 x 1023 atoms 1.7 x 1025 Kr atoms x (1 mole Kr)/(6.022 x 1023 Kr atoms) = 28 moles Kr (rounded to two sig figs)
The answer is 3,587 moles.
The answer is 0,465 moles.

H2O is water. One mole of water contains 2 moles of hydrogen atoms. Therefore, 10.7 moles of water contain 21.4 moles of hydrogen atom.
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
The answer is 6,31 moles Ag.
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
each mole has avogadro's number of atoms in it, which is 6.02 x 10 to the 23rd power. so, 4 x 6.02 x 10 23 power of atoms
