Answer:
Moles = 8 moles
Solution:
Molarity is given as,
Molarity = Moles / Volume of Solution ------ (1)
Data Given;
Molarity = 2 M
Volume = 4 L
Solving eq.1 for Moles,
Moles = Molarity × Volume of Solution
Putting values,
Moles = 2 mol.L⁻¹ × 4 L
Moles = 8 moles
Equal is the answer
Hope this helps
Explanation:
As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.
As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.
So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.
Therefore, concentration of chlorine ions will be calculated as follows.
Concentration of ions =
= 0.6 mM
Thus, we can conclude that the concentration of chloride ions is 0.6 mM.
Among the choices the statement about crystal lattice energy is best supported by the information in the table is <span>The lattice energy increases as the charge of anions increases, as shown by LiF and LiCl. The answer is B.
