Solve the following problems and show complete solutions. The final answers must be reported in proper units and number of significant figures. Assume that all solutions were prepared at 25°C, and the solutes were completely dissolved. Molar masses should be based on the Periodic Table provided. Density values are provided if needed. In the lead content analysis of a wastewater sample, 50.00 mL of the original sample was taken and diluted with 150.00 mL deionized water. The diluted sample was found to have a lead content of 17.8 ppb. What is the lead content (in ppb) of the original wastewater sample? DENSITY VALUES AT 25°C Ethanol: 0.789 g/mL Acetic Acid: 1.05 g/mL Water: 0.997 g/mL
