Fill in the Blanks. - A 1:10 ration, means that the final solution has been diluted ....... fold. - If the original solution has 0.1 mole per liter and the ration is 1:5, the final concentration is ........ moles per liter. - You have a 1 molar solution and need to do a 1:5 dilution to prepare a 40ml solution. This means you need ....... ml of the original 1 molar solution for this dilution.
