A. Explain how to prepare 25 liters of a 0.10 M BaCl2 solution, starting with solid BaCl2.
b. Specify the volume of the solution in (a) needed to get 0.020 mol of BaCl2.
a. Molarity is an expression of the moles of solute per liter of solution, which can be written:
molarity (M) = moles solute / liters solution
Rearranging this equation, we get:
moles solute = molarity x liters solution
So, for this ...
