0.550 mole BaCl2 x 6.02x10^23 formula units/mole x 3 atoms/formula unit = 9.93x10^23 atoms
* NaI + AgNO3 = AgI(s) + NaNO3* CH3COONa + AgNO3 ----------CH3COOAg + NaNO3These reagents doesn't react.* 2 Na3PO4 + 3 BaCl2 = 6 NaCl + Ba3(PO4)2(s)* Na2SO4 + BaCl2 = 2 NaCl + BaSO4(s)
Chemical fomula is BaCO3.So there are 6 atoms.
The potassium chloride formula unit (KCl) contain two atoms (K and Cl). Potassium chloride is an ionic compound and therefore does not have true molecules at all.
Barium hydroxide (the formula is Ba(OH)2) contain two hydrogen atoms.
Ammonium chloride has the formula of NH4Cl. Thus, in each mole there are 4 moles H, 1 mole N and 1 mole Cl for a total of 6 moles of atoms. Then 6.02x10^23 atoms/mole x 6 moles = 3.6x10^24 atoms.

Chemical fomula is BaCO3.So there are 6 atoms.
.256 molar= 256 mols of solute per 1000ml of solution. Since there are 1000ml in 1L, there are 256 mols of BaCl2 for every liter. Multiply this by 1.5 and you get a total of 384 mols of BaCl2 in 1.5L of a .256 molar solution
Hydrogen chloride molecule (HCl) has two atoms.
Barium nitrate, Ba(NO3)2: Ba - 1 atom Nitrogen - 2 atoms Oxygen - 6 atoms Total - 9 atoms
The potassium chloride formula unit (KCl) contain two atoms (K and Cl). Potassium chloride is an ionic compound and therefore does not have true molecules at all.
The correct formula of sodium chloride is NaCl. This molecule has two atoms - sodium and chlorine.
Barium hydroxide (the formula is Ba(OH)2) contain two hydrogen atoms.
Ba(C2H2O2)2 has one atom in Barium, four in Carbon, four in Hydrogen, and four in Oxygen, meaning there are 13 total atoms. 1+4+4+4=13
The minimum formula unit of barium hydroxide is Ba(OH)2. This contains one barium atom and two each of oxygen and hydrogen, for a total of five.
Ammonium chloride has the formula of NH4Cl. Thus, in each mole there are 4 moles H, 1 mole N and 1 mole Cl for a total of 6 moles of atoms. Then 6.02x10^23 atoms/mole x 6 moles = 3.6x10^24 atoms.
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.
