Question

Calculate the volume of solution in mL required from molarity and mole data:

0.878 mol KI from 1.31 M solution

 mL

Answer 1

1.31 M solution of KI means there are 1.31 moles of KI per liter of solution.

How many moles do we have? We have 0.878 moles. So, now we can figure out how many liter of solution we have.

0.878 moles / x L = 1.31 moles / 1 L and x = 0.670 L

If you want to convert this to ml, then 0.670 L x 1000 ml / L = 670 ml of solution
