What is the molarity of 3.68mL of a solution containing 0.0025 moles of calcium chloride?

Molarity = mol/ L = 0.0025 / 0.00368 L = .679 M

I agree with Beth.

Well, let's see. To find the molarity of a solution, you need to divide the moles of solute by the volume of the solution in liters. Since we have the volume in mL, we need to convert it to liters first.

So, 3.68 mL is 0.00368 liters (because there are 1000 mL in a liter).

Now, let's divide the moles of calcium chloride (0.0025 moles) by the volume in liters (0.00368 L):

0.0025 moles / 0.00368 L = 0.680 molarity

Therefore, the molarity of the solution is 0.680 M. But wait, don't calcium chloride solutions deserve a round of applause? 🎉

To find the molarity of a solution, you need to know the number of moles of solute (calcium chloride) and the volume of the solution. In this case, the number of moles of calcium chloride is given as 0.0025 moles and the volume of the solution is 3.68 mL.

Step 1: Convert the volume from milliliters (mL) to liters (L).
To convert mL to L, divide the volume by 1000:
3.68 mL ÷ 1000 = 0.00368 L.

Step 2: Use the formula for molarity.
Molarity (M) is defined as the number of moles of solute divided by the volume of the solution (in liters).
Molarity (M) = Moles of solute / Volume of solution (in L)

Step 3: Calculate the molarity.
Molarity (M) = 0.0025 moles / 0.00368 L = 0.6793 M.

Therefore, the molarity of the solution is 0.6793 M.

To find the molarity, you need to first understand that molarity is a measure of the concentration of a solution, expressed as the number of moles of solute per liter of solution.

In this case, you are given the volume of the solution (3.68 mL) and the number of moles of the solute (0.0025 moles of calcium chloride). To calculate the molarity, you will need to convert the given volume to liters.

Step 1: Convert the volume to liters.
There are 1000 mL in 1 L, so you can convert the given volume as follows:
3.68 mL ÷ 1000 = 0.00368 L

Step 2: Calculate the molarity.
The molarity (M) is calculated by dividing the number of moles of solute by the volume of the solution in liters:
Molarity = moles of solute / volume of solution (in liters)

M = 0.0025 moles / 0.00368 L ≈ 0.680 M (rounded to three decimal places)

Therefore, the molarity of the solution is approximately 0.680 M.
