There are 7 atoms: 1 calcium, 2 carbon, and 4 oxygen.
The answer is 4,745.10e21 atoms.
In calcium carbide (CaC2) are 1 atom of Calcium and two of Carbon, so totally three atoms of two elements
There are 15.432 grains in one gram224 grains=1 dwt / 1 { pennyweight } =.05 troy ounce / 1 gram=.643 pennyweight / 1 grain = 0.0648 grams / 4 grains = 1 carat / 15.432 grains = 1 Gram
One mole of anything, no matter what the element is, is Avogadro's number, which is 6.02 * 10^23 atoms. One mole of Calcium is equal to it's atomic weight in grams : 1 mole Ca = 40.08 g = 6.02 * 10^23 atoms There is a 1000mg in a gram. 1000mg * 40.08g = =40,080mg of Ca per mole If you have 8.6mg of Ca that is 8.6mg / 40,080mg = .00021457 of a mole of calcium so just multiply that by Avogadro's number to give you number of atoms: .00021457 * 6.02 * 10^23 atoms = 1.292 * 10^20 atoms of Ca
There are 6.023 x 10^23 atoms in each mole of calcium. I mole of calcium is 40 g, so 1 g contains 6.023 x 10^23/40 atoms = 1.506 x 10^24
Calcium nitrate has 9 atoms.
6.022
1
129 grams calcium (1 mole Ca/40.08 grams calcium)(6.022 X 10^23calcium atoms/1 mole Ca) = 1.94 X 10^24 atoms of calcium
1 molecule of Calcium Carbonate -CaCO3, contains 3 oxygen atoms.
3; 1 calcium and 2 iodine
The formula unit for calcium nitride is Ca3N2. That would be 3 atoms of calcium and 2 atoms of nitrogen, for a total of 5 atoms in a formula unit.

3; 1 calcium and 2 iodine
Two atoms. One calcium (Ca) and one oxygen (O).
175 g Ca (1 mol / 40.078 g) (6.022x10^23 atoms / 1 mol) = 2.63x10^24 Ca atoms There are 2.63x10^24 c.alcium atoms in 175 grams of calcium.
