18 an important environmental consideration is the appropriate disposal of cleaning solvents. an environmental waste treatment company analysed a cleaning solvent, j, and found it to contain the elements carbon, hydrogen, and chlorine only. the chemical composition of j was determined using different analytical chemistry techniques. combustion reaction: combustion of 1.30 g of j gave 0.872 g co2 and 0.089 g h2o. precipitation reaction with agno3(aq): 0.535 g of j gave 1.75 g agcl precipitate. (a) determine the percentage by mass of carbon and hydrogen in j, using the combustion data. (3) (b) determine the percentage by mass of chlorine in j, using the precipitation data. (1) (c) the molar mass was determined to be 131.38 g mol–1. deduce the molecular formula of j.
