What is the mass number of MgCl2?

Now, we are given with the compound i.e. magnesium chloride having the chemical formula MgCl2. The atomic mass of magnesium is 24 u, whereas chlorine has the atomic mass 35.5 u. Therefore, the formula unit mass of magnesium chloride is 95 u.

What is the equivalent weight of MgCl2?

Answer: The Magnesium chloride’s equivalent weight is 47.6 gram.

How many moles of ions are present in 27.5 g of MgCl2?

Explanation: Moles of magnesium salt = 27.5⋅g95.21⋅g⋅mol−1 = 0.289⋅mol. There are thus 2×0.289⋅mol chloride ions , and 0.289⋅mol magnesium ions , almost an entire mole of ions.
