Una muestra de 0,0341 moles de FeCl3 se disuelve en agua para dar 25 ml de solución. ¿Cuál es la molaridad de la solución?

The molarity of the solution is 1, 364 M.

Explanation:

Molarity is a concentration measure that expresses the moles of solute (in this case NaOH) per liter of solution (1000ml). We perform a simple rule of three calculation to obtain the molarity:

25 ml solution 0,0341 moles of FeCl3

1000ml solutionx=

x=(1000 ml solution x 0,0341 moles of FeCl3)/ 25 ml solution

x= 1,364 moles of FeCl3 ---> The solution is 1,364 M

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
