In a student experiment, the empirical formula of a copper halide was found by adding aluminum metal to an aqueous solution of the halide, displacing copper metal. the copper metal was filtered, washed with distilled water, dried, and weighed; three separate determinations were performed. the copper halide solution contained 42.62 g of copper chloride per liter. the student recorded the following experimental data. trial volume of copper chloride solution (ml) mass of filter paper (g) mass of filter paper with copper (g) a 49.6 0.908 1.694 b 48.3 0.922 1.693 c 42.2 0.919 1.588 part a write the empirical formula of copper chloride based on the experimental data.

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
