How many moles of ions are in 285 ml of 0.0150 m mgcl2?

Answer : The number of moles of and ions are 0.00428 and 0.00856 moles respectively.

Explanation :

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

In this question, the solute is .

Given :

Volume of solution = 285 mL = 0.285 L    (1 L = 1000 mL)

Molarity = 0.0150 M

Now put all the given values in this formula, we get:

Thus, the number of moles of are 0.00428 moles.

By the stoichiometry we can say that, 1 moles of dissociates to give 1 mole of ion and 2 moles of ions.

So,

Number of moles of ion = 0.00428 mole

Number of moles of ion = 2 × 0.00428 = 0.00856 mole

Therefore, the number of moles of and ions are 0.00428 and 0.00856 moles respectively.
