Calculate the volume in liters of a 0.195m potassium dichromate solution that contains 100. g of potassium dichromate (k, cr, o2). be sure your answer has the correct number of significant digits. |l x s ?

The volume of solution is 1.74 L

Explanation:

To calculate the number of moles, we use the equation:

Given mass of potassium dichromate = 100 g

Molar mass of potassium dichromate = 294.185 g/mol

Putting values in above equation, we get:

To calculate the volume of solution, we use the equation:

We are given:

Molarity of solution = 0.195 M

Moles of potassium dichromate = 0.34 moles

Putting values in above equation, we get:

Hence, the volume of solution is 1.74 L

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
