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

∙ 12y agoIn 2 moles of MgCl2, there are 4 moles of Cl- ions. There are 6.022 X 1023 Cl- ions in a mole of Cl- ions. So,
4 moles Cl- ions X 6.022 X 1023 Cl-/1 mole Cl- = 2.409 X 1024 Cl- ions.

How many formula units make up 11.6g of mgcl2?
Magnesium chloride (MgCl2) has a molecular weight of 95.21 grams per mole. 11.6 grams of MgCl2 is therefore .122 moles.
How many moles in 53.8 g of magnesium chloride?
Magnesium chloride, MgCl2, has a molecular mass of has a molar mass of 95.21 g/mol. So, 53.8 g MgCl / 95.21 g/mol is 0.565 mol MgCl2.
How many atoms are in 4 moles of MgCl2?
1 mole of any substance contains 6.02 x 1023 constituent particles, correct to three significant figures (avogadro constant).Number of molecules of 4 moles of MgCl2 = 4 x 6.02 x 1023In every molecule of MgCl2 there are 3 atoms.Thus, number of atoms in 4 moles of MgCl2 = 3 x 4 x 6.02 x 1023 = 7.22 x 1024
How many atoms are n 4.0 moles of MgCl2?
MgCl2 is an ionic compound with the Mg2+ cation and the Cl- anion in a 1:2 ratio. In each formula unit of MgCl2 there are two Mg2+ and one Cl- ion. So in 4 moles of MgCl2 there will be 12 moles of ions.

In the reaction MgCl2 plus 2KOH gives magnesium hydroxide plus 2KCl if 3 moles of MgCl2 are added to 4 moles KOH what determines how much magnesium hydroxide is made?
MgCl2(aq) + 2KOH(aq) --> Mg(OH)2(s) + 2KCl(aq)It is the molar ratio in the equation. Every mole of magnesium chloride requires 2 moles of potassium hydroxide. Thus 3 moles would need 6 moles of alkali for complete reaction. We don't have that much, so potassium hydroxide is the limiting reactant and we can only use 2 moles of the magnesium chloride and produce 2 moles of magnesium hydroxide.
