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.

Assume the data below was collected for two different sample solutions using the same experimental procedure you carried out. Based on the two lines shown below, which solution (orange data points or blue data points) corresponds to the sample that would look DARKER in terms of how much light goes through the glass. 0.9 y= 4.7713x - 0.0728 R0.99953 0.8 0.7 0.6 0.5 0.4 0.3 0.2 y1.414x - 0.0546 R0.99642 0.1 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.1 [Concentration, M] orange data points (lower line) blue data points (upper line) Absorbance
