2.4/4 = 0.6 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.
To calculate the number of moles from the number of atoms, we need to divide the number of atoms by Avogadro's number (6.022 × 10^23), which gives 3.59 moles of iron atoms.
To find the number of moles, you need to divide the given number of iron atoms by Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. Therefore, for 5.22 x 10^22 iron atoms, the number of moles would be approximately 0.0867 moles.
avogadro's constant is the number of atoms (or molecules, as in the case of compounds) contained in a mole of a substance. roughly, then, in 4 moles of gold there are 4 x 6.02 x 10 to the 23rd power atoms or two septillion, four hundred eight sextilllion atoms.

In 1.5 moles of CaCl2, you would have 3 moles of ions or atoms of calcium and 3 moles of ions of chloride. Since CaCl2 dissociates into 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), this means you would have 3 moles of calcium ions and 6 moles of chloride ions in total.
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.
To calculate the number of moles from the number of atoms, we need to divide the number of atoms by Avogadro's number (6.022 × 10^23), which gives 3.59 moles of iron atoms.
Avogadro's number times 5.6 (or about 33.6 times ten to the 23rd power.
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)
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
To find the number of moles, you need to divide the given number of iron atoms by Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. Therefore, for 5.22 x 10^22 iron atoms, the number of moles would be approximately 0.0867 moles.
very roughly 5 moles...avagadros number = 6.022 x 1023 just devide 30 by this number
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.

The answer is 6,31 moles Ag.
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.
