A student decides to use the technique employed in Part B of this lab to determine the density of vodka. He first fills a buret with vodka to an initial volume of 1.52 mL. He then drains out some of the vodka into an empty beaker with a mass of 13.687 g. The final buret volume is 9.62 mL. If the combined mass of the beaker and vodka is 21.123 g, what is the the density of the vodka
