Answer 1

The question is incomplete, here is the complete question:

Calculate the volume in liters of a 0.13 M potassium dichromate solution that contains 200. g of potassium dichromate . Round your answer to 2 significant digits.

Answer: The volume of solution is 5.2 L

Step-by-step explanation:

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

`\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}* \text{Volume of solution (in L)}}`

We are given:

Molarity of solution = 0.13 M

Given mass of potassium dichromate = 200. g

Molar mass of potassium dichromate = 294.15 g/mol

Putting values in above equation, we get:

`0.13M=\frac{200}{294.15* \text{Volume of solution}}\\\\\text{Volume of solution}=(200)/(294.15* 0.13)=5.23L`

Hence, the volume of solution is 5.2 L
