A chemist prepares a solution of magnesium chloride MgCl2 by measuring out 49.mg of MgCl2 into a 100.mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Cl−anions in the chemist's solution. Be sure your answer is rounded to the correct number of significant digits.

 Molarity of anions in the chemist's solution is 0.0104 M

Explanation:

Molarity : It is defined as the number of moles of solute present per liter of the solution.

Formula used :

where,

n= moles of solute

= volume of solution in ml = 100 ml

Now put all the given values in the formula of molarity, we get

Therefore, the molarity of solution will be

As 1 mole of gives 2 moles of

Thus  moles of gives =

Thus the molarity of anions in the chemist's solution is 0.0104 M

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
