Answer: 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

First convert the 590.0 grams of water to liters of water.
590.0 grams x (1 L / 1000 grams) = 0.59 L
Since we're dealing with concentration, recall this formula:
Molarity (M) = (moles of solute) / (liters of solution)
We know the Molarity and the Liters
0.82 M = (moles) / 0.59 L
To find the moles multiply 0.59 on both sides.
The result is 0.4838 moles of CaCl (the solute).
Then change moles into grams because the question wants grams.
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass which is 110.986.
(0.4838 moles CaCl2) x (110.986 g CaCl)/ 1 mol CaCl2
<h2><u>
= 53.7g CaCl</u></h2>
