Consider the process of diluting 1.2 M NH4Cl solution to prepare 1.4 L of a 0.25 M NH4Cl solution. Determine if each of the follow statement is True or False. (1) The dilution equation M1V1 = M2V2 is a balance of moles of the solute, which is NH4Cl in this question.

True the dilution formula is a balanced of mole of the solute..

Explanation:

M1V1 = M2V2

When M1= 1.2M, M2= 0.25M V2= 1.4L and V1= ?

Then V1= 0.25*1.4/1.2

= 0.29

This indicate that 0.29L of the 1.2M NH4Cl will be dilluted to 0.25M in 1.4L of the solution

The mole number of the solute remain constant

b. atoms in metallic solids are not arranged in a regular pattern

explanation:
