How many grams of Al(no2)3 should be added to 1.3L of water to prepare a 2.0M solution

429 grams of  should be added to 1.3 L of water to prepare 2.0 M solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,

n = moles of solute =  

= volume of solution in Liters  

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

Therefore, 429 grams of  should be added to 1.3 L of water to prepare 2.0 M solution

explanation:

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
