What is the concentration of a solution which contains 1 mole of CaCl2 dissolved in 2000mL of solutions?
In what units? molarity? molality, percent by mass? percent w/v?
For molarity, M = moles/L solution.
So M = 1 mole/2 L = 0.5 M.
0.5 M
But it's bettet to mention as 0.5 F.
F specifies formality.
Since the solute is an electrolyte or in other words calcium chloride ionize in water (dissociate), we can report the answer in 'F'.
To determine the concentration of a solution, we need to consider the amount of solute (in this case, CaCl2) dissolved in a given amount of solvent (in this case, the solution with a volume of 2000 mL).
The concentration of a solution is commonly expressed in moles per liter (mol/L) or molarity (M). To calculate the concentration, we will need to convert the given volume from milliliters (mL) to liters (L).
First, convert 2000 mL to liters:
2000 mL ÷ 1000 = 2 L
Now, we have the volume in liters. Next, we divide the number of moles of the solute by the volume of the solution in liters to find the concentration.
The solution contains 1 mole of CaCl2, so the concentration can be calculated as follows:
Concentration = Number of moles / Volume of solution
Concentration = 1 mole / 2 L
Therefore, the concentration of the solution containing 1 mole of CaCl2 dissolved in 2000 mL (or 2 L) of solution is 0.5 M (mol/L) or 0.5 moles per liter.
