Explanation:
Molar mass of NaCl = 58.5 g
Number of moles contained in 10 g of NaCl = 10 g/58.5 g = 0.17 moles
If 1 mole of NaCl contains 6.02 * 10^23 atoms
0.17 moles of NaCl contains 0.17 * 6.02 * 10^23 atoms = 1.02 * 10^23 atoms
Molar mass of Fe II chloride = 126.751 g/mol
Number of moles = 10 g/126.751 g/mol = 0.0789 moles
Number of atoms = 0.0789 moles * 6.02 * 10^23 atoms = 4.7 * 10^22 atoms
Molar mass of Na = 23 g/mol
Number of moles = 10g/23 g/mol = 0.43 moles
Number of atoms = 0.43 moles * 6.02 * 10^23 atoms = 2.59 * 10^ 23 atoms
Answer:
The concentration of the hydroxide ion concentration for muriatic acid is 3.16 * 10^-12 M
Explanation:
Muriatic acid = HCl
pH = 2.5
pH = -log[H+]
pOH = 14 - pH
pOH = 14 - 2.5 = 11.5
pOH = -log [OH-]
11.5 = -log [OH-]
[OH-] = 10^-11.5
[OH-] = 3.16 * 10^-12 M
The concentration of the hydroxide ion concentration for muriatic acid is 3.16 * 10^-12 M

Since both sides have to be equal to each other, subtracting the left side from the right side will leave you with the other reactant.
On the right side, you have 1 sodium, 2 carbon, 5 hydrogen, and 3 oxygen.
If you take away 1 sodium, 1 oxygen, and 1 hydrogen you are left with 2 carbon, 4 hydrogen, and 2 oxygen.
This is written as CH3COOH
AKA Acetic Acid
