1,33.10e24----------------------------x
x = 1,33.10e24/6,022140857.10e23 = 2,2 moles Zn
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
The result is 0,921.10e14 moles.
6.022*10^23 * 0.6 or about 3.61*10^23
As a chemical element zinc contain only zinc atoms.
The chemical formula for zinc floride is ZnF2. Thus, a single molecule of zinc floride contains one zinc atom and two floride atoms, for a total of three atoms.
The answer is 2,7 moles.
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
15.0553*1023 Zn atomsBy definition of the 'mole' there are ALWAYS 6.02214*1023 particles (of any kind) in ONE mole of that matter. (This BIG number is called the Avogadro number or constant)So this is true for atoms Zn in 1 mole pure zinc, for H2O molecules in 1 mole water, even for sand particles in 1 mole sand (but there is not so much sand in a desert)
3.21 x 10^23
Zn + H2SO4 ---> ZnSO 4 + H2 so one mole of zinc and 1 mole of sulfuric acid produces one mole of hydrogen molecules and thus two moles of hydrogen atoms. So 0.36 moles of zinc will produce 0.36 moles of hydrogen molecules and thus 0.72 moles of hydrogen atoms.
The number of atoms is identical.
There are : 1 zinc atom 2 chlorine atoms 6 oxygen atoms in this zinc chlorate molecule.
0,356 moles of zinc contain 23,27 g.
Molar mass of Zinc = 65.4 g mol-1 No. of moles of 20.0 g of Zinc = 20.0 / 65.4 = 0.305810397 mol No. of atoms = 0.305810397 L (where L is the Avogadro constant) = 1.8416 x 1023
6.228 mole of zinc atom
Zinc is an atom however there are 30 proton and electrons in a zinc atom. The number of atoms depends on the molecule, I'm sorry
Zinc and hydrochloric acid
