To go from moles of an ionic compound to the number of ions you must multiply your number of moles by Avogadro's number (Avogaro's number is approximately 6.02 • 10^23). So lets say you have 2 moles of a sulfate ion you would do (2moles)(6.02 • 10^23 ions/mole) = 1.20 • 10^24
Avogadro's Number is used to convert any substance between moles and # of atoms/molecules/ions
There are 5.2 moles of ions in 2.6 moles of K2SO4. This is because each formula unit of K2SO4 dissociates into three ions: 2K+ ions and 1 SO4^2- ion. Thus, for every mole of K2SO4, you have 3 moles of ions.
The number of moles is 8,00944733981.10e23.
There are 6 moles of nitrate ions in 2 moles of magnesium nitrate. This is because there are 3 nitrate ions (NO3-) in each formula unit of magnesium nitrate (Mg(NO3)2). So, 2 moles of Mg(NO3)2 would contain 6 moles of nitrate ions.
Each molecule CoCl2 ionises in three single ions (1 Co2+ and 2 Cl- ions), so 0.27 mol CoCl2 gives 3 * 0.27 = 0.81 mole ions (0.27 mole Co2+ and 0.54 mole Cl- ions)
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.
When Na2CO3 dissociates, it produces 3 moles of ions: 2 moles of Na+ ions and 1 mole of CO3^2- ions. So, if you have 0.5 moles of Na2CO3, you would produce 1.5 moles of ions in total.
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
There are 5.2 moles of ions in 2.6 moles of K2SO4. This is because each formula unit of K2SO4 dissociates into three ions: 2K+ ions and 1 SO4^2- ion. Thus, for every mole of K2SO4, you have 3 moles of ions.

2 moles of Ca and 4 moles of OH
A neutral solution of about 7 pH.
There are 6 moles of nitrate ions in 2 moles of magnesium nitrate. This is because there are 3 nitrate ions (NO3-) in each formula unit of magnesium nitrate (Mg(NO3)2). So, 2 moles of Mg(NO3)2 would contain 6 moles of nitrate ions.
Each molecule CoCl2 ionises in three single ions (1 Co2+ and 2 Cl- ions), so 0.27 mol CoCl2 gives 3 * 0.27 = 0.81 mole ions (0.27 mole Co2+ and 0.54 mole Cl- ions)
Mg2+ + 2 Cl- are in 1 : 2 ratio (of ions) so also 0.25 : 0.50 mole ratio
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.
To find the concentration of nitrate ions in the mixture, we first calculate the moles of nitrate ions from each salt using the formula moles = concentration x volume. For potassium nitrate: 0.120 mol/L x volume = moles of nitrate ions. For iron (II) nitrate: 0.160 mol/L x volume = moles of nitrate ions. Add the moles of nitrate ions from both salts to get the total moles of nitrate ions in the mixture. Finally, divide the total moles of nitrate ions by the total volume of the mixture to get the concentration of nitrate ions in the mixture.
No, the moles of silver ions in water depend on the concentration of the silver ions present, while the moles of silver ions in a silver nitrate solution depend on the amount of silver nitrate dissolved. The two may not be equal unless the silver nitrate is completely dissociated into silver ions in water.
