You are given a (1.057x10^0) M solution of sodium chloride. Using a serological (also called a Mohr, or calibrated pipette), you pipette (7.8900x10^1) ml into a 250 mL volumetric flask, and dilute to the mark with appropriate mixing. Using a serological (also called a Mohr, or calibrated pipette), you then pipette (2.39x10^1) ml of the solution from the 250 ml flask into a 100 ml volumetric flask, and dilute to the mark with appropriate mixing. What is the dilution factor of your final solution in the 100 ml flask? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: X10
