How many moles of barium chloride are present in 6.5l of a 3m solution

The answer to your question is 19.5 moles

Explanation:

Data

moles = ?

Volume = 6.5 l

Molarity = 3 M

Molarity is a unit of concentration that relates the number of moles by the volume (liters).

Formula

Molarity = moles / Volume

-Solve for moles

moles = Molarity x Volume

-Substitution

moles = 3 x 6.5

-Result

moles = 19.5

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
