In exactly one gram formula unit, there are always Avogadro's Number of individual formula units. Therefore, the number of gram moles or gram formula units in 3.61 X 1023 formula units is* 3.61/6.022 or 0.599, to the justified number of significant digits.
______________________________
The factor 1023 occurs in both numerator and denominator and therefore need not be written.
3.58 E23 formula units is equal to 3.58 E23 molecules of ZnCl2. There are 6.022 E23 atoms in a mole, so there are 0.5945 moles present.
6.02x10(to the power of 23). This is the calculation of 1 mol. Use this to times the 3.12 moles of ZnCl2. Then times the 2 atoms of Cl2. The answer is 3.75648x10(to the power of 24).
0.59448688143474 assuming you meant 10^23 instead of 1023
3,85 g zinc is equivalent to 0,059 moles.

.21 moles/liter * .0655 L = 0.013755 moles AlCl3 .013755 * 3 moles Cl / 1 mole AlCl3 = 0.041265 moles Cl * avagadro's number = number of chloride ions
Molarity is moles/liter, so in order to find the moles of a substance in a given volume, simply multiply molarity with volume (in liters). n=M*V
Two Chloride ions (2Cl-) ions are needed with their -1 charge on each one to cancel out the +2 charge of the single Magnesium ion (Mg2+). So Magnesium Chloride would have the chemical formula: MgCl2
n = 5.670�10�3 molCl� the molar formula appears above.
Aluminum chloride contains 3 chlorine atoms per molecular unit. Therefore, in 3 moles there are 3 times Avogadro's number of chloride ions = 1.807 X 1024.
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
There are two moles of sodium ions in two moles of sodium chloride.
2.4088 x 1024 chloride ions
1.20442 x 1024 chloride ions
The formula unit for calcium chloride is CaCl2. There are two chloride ions in one formula unit of calcium chloride. We can also say that there are two moles chloride ions in one mole of CaCl2.
.21 moles/liter * .0655 L = 0.013755 moles AlCl3 .013755 * 3 moles Cl / 1 mole AlCl3 = 0.041265 moles Cl * avagadro's number = number of chloride ions
I assume that is 28.0 grams.28.0 grams MgCl2 (1 mole MgCl2/95.21 grams)= 0.294 moles magnesium chloride==========================Now,One mole Mg 2+ = 0.294 moles Mg 2+ ions=============================2 moles Cl - = 0.588 moles Cl - ions=========================
Molarity is moles/liter, so in order to find the moles of a substance in a given volume, simply multiply molarity with volume (in liters). n=M*V

The chemical formula for calcium chloride is CaCl2, and its formula weight is 110.99. The formula shows that each formula weight of calcium chloride contains one mole of calcium ions. In 166.5 grams, there are 166.5/110.99 or 1.500 formula weights of calcium chloride and the same number of moles of calcium ions.
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
