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.
AlCl3
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
.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
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.
Aluminum is 3+ and chloride is 1-. So, you need 3 chloride ions to neutralize 1 aluminum ion.
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
AlCl3
Aluminium chloride, AlCl3, dissociates into one Al3+ ion and three Cl- ions when it is dissolved in water. So in total, there are four ions in aluminium chloride.
There will be 6.022 x 10^23 sodium ions in 2.00 mol of NaCl. This is because one mole of NaCl contains one mole of sodium ions, and Avogadro's number (6.022 x 10^23) represents the number of entities in one mole of a substance.
2.4088 x 1024 chloride ions
There are 2 moles of KCl in the sample, so there are 2 moles of chloride ions as well. Since each molecule of KCl contains 1 chloride ion, there are 2 moles of chloride ions in total.
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.
0,6 moles of (ClO4)3- and 0,2 mol Al
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=========================
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
