In determining the density of water using a pycnometer, what should be the first step to be done before starting the experiment? Clean the pycnometer with sodium hydroxide and hydrochloric acid, then dry it completely. Fill the pycnometer with water. Weigh the empty pycnometer. O Clean the pycnometer with HCI followed by distilled water, then dry it completely. Which of the statements is true and correct? * Using a pycnometer is an inaccurate and imprecise way of determining the density of liquids. O The density of water can only be measured directly by using a pycnometer. A pycnometer is a type of glass flask with a close-fitting ground glass stopper with a capillary hole through it. O The density of liquids can only be measured by using a pycnometer.

A chemist must dilute 16.6mL of 2.03M aqueous zinc nitrate ZnNO32 solution until the concentration falls to 1.00M. She'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in milliliters. Round your answer to 3 significant digits.
A chemist must dilute 18.7mL of 23.4μM aqueous mercury(II) iodide HgI2 solution until the concentration falls to 16.0μM .

It is recommended that drinking water contain 1.6ug/ml (parts per million) flouride (F-) for prevention of tooth decay. Consider a reservoir with a depth of 30.0 m and a diameter (diameter = 2 r) of 7.60 x10^4 m. (The volume is pi r^2 h) Calculate the amount of F- in grams that were added to the reservoir to give 1.6 ug/ml. How many grams of sodium flouride NaF, contain this much flouride? Note: NaF ---- Na+ + F- Please explain in depth and an easy to follow step by step process on how to solve. Thanks
Chlorine is used to disinfect swimming pools. The accepted concentration for this purpose is 1 ppm chlorine or 1 g of chlorine per million g of water. Calculate the volume of a chlorine solution (in milliliters) a homeowner should add to her swimming pool to achieve 1.00 ppm chlorine if the solution contains 6.00 percent chlorine by mass and there are 8.45 × 104 gallons of water in the pool. (1 gallon = 3.79 L; density of liquids = 1.00 g/mL.)
