Chemistry Problem-Solving: Determining the Molarity of Cobalt(II) Solution

How can we determine the molarity of the cobalt(II) solution?

Based on the given data and balanced reaction, what steps can we take to find the molarity of the cobalt(II) solution?

Solution:

To find the molarity of the cobalt(II) solution, we can follow these steps:

1. Convert the volume of the vanadate solution to liters by multiplying the volume in milliliters by 10^-3.

2. Use the mole ratio from the balanced equation to calculate the number of moles of VO4-2 to CO+2.

3. Calculate the moles of VO4-2 using the molarity and volume of the vanadate solution.

4. Use the mole ratio to determine the moles of CO+2.

5. Convert the volume of the cobalt(II) solution to liters.

6. Calculate the molarity of the cobalt(II) solution by dividing the moles of CO+2 by the volume in liters.

By following these steps and substituting the values into the equation, we can determine the molarity of the cobalt(II) solution.
