A 15.00 g metal sphere was found to have a diameter of 1.85 cm. The volume of a sphere is V = (4/3)pir^3. Calculate the density of the sphere and assuming that the sphere is made out of one of the elements, aluminum, chromium, iron, lead, titanium or zinc, determine its composition. A 5581 gram irregular object made out of one of the metals in #6 raises the water level in a graduated cylinder from the 17.6 mL level to...

Question 2 of 5 A 0.4686 g sample of pewter, containing tin, lead, copper, and zinc, was dissolved in acid. Tin was precipitated as Sno, .4H, O and removed by filtration. The resulting filtrate and washings were diluted to a total volume of 200.0 mL. A 20.00 mL aliquot of this solution was buffered, and titration of the lead, copper, and zinc in solution required 35.16 mL of 0.001543 M EDTA. Thiosulfate was used to mask the copper in a...
