1.A student delivered 11.85 mL (V1) of 2.49 % stock solution (M1) using a graduated pipette into a 50.00 mL (V2) volumetric flask. Distilled water was added to the flask to the graduation mark and mixed well.
Using the dilution equation (provided below), calculate the concentration of the diluted solution.

(M1)(V1) = (M2)(V2) Report your answer to 3 decimal places.

2.Density is given by the equation density=mass/vol (d=m/V). Given that the density of magnesium is known to be 1.74 g/mL, what volume of water (in mL) would a magnesium cylinder with a mass of 28.85 grams displace?
Report your answer to 2 decimal places.
