It's MgCl2, and yes, it is soluble. It's an ionic compound, and ionic compounds are very polar. Water is polar as well, so magnesium chloride easily dissolves in water.

How many atoms does MgCL have?

If unbalanced the molecule MgCl will have one atom of Mg and one of Cl and therefore two atoms. in real life you would not have MgCl, you would have MgCl2 (where 2 is a subscript). This means there is one atom of Mg and two of Cl and therefore 3 atoms in total.


Is chalk soulble?

Chalk is essentially calcium carbonate, CaCO3, and in not soluble in water to any significant extent.


What is the molarity of 0. 96 g MgCl2 in 500 ml of solution?

To find the molarity of MgCl₂, first calculate the number of moles of MgCl₂ in 0.96 g. The molar mass of MgCl₂ (Mg: 24.31 g/mol, Cl: 35.45 g/mol × 2) is approximately 95.21 g/mol. Thus, moles of MgCl₂ = 0.96 g / 95.21 g/mol ≈ 0.0101 moles. Since the volume of the solution is 500 ml (0.5 L), the molarity (M) is calculated as moles/volume = 0.0101 moles / 0.5 L = 0.0202 M.


How many magnesium atoms in MgC12?

In the chemical formula MgCl₂, there is one magnesium (Mg) atom. The formula indicates that for every magnesium atom, there are two chloride (Cl) atoms. Therefore, MgCl₂ contains a total of one magnesium atom.


What is the percent composition of CI in MgCI2?

To find the percent composition of chlorine (Cl) in magnesium chloride (MgCl₂), first calculate the molar mass of MgCl₂. The molar mass of magnesium (Mg) is approximately 24.31 g/mol, and that of chlorine (Cl) is about 35.45 g/mol. Thus, the molar mass of MgCl₂ is 24.31 + (2 × 35.45) = 95.21 g/mol. The percent composition of Cl is then calculated as (2 × 35.45 / 95.21) × 100%, which is approximately 74.4%.
