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

since electrons are negative the answer is neagtaive

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
