Dimensional analysis simply refers to the inclusion of units in an equation. After setting up the solution map, dimensional analysis can be used to set up the conversion factors that lead to the desired values vithin this map. The correct setup of an equation can be verified by checking if the result will only have the desired units after unit cancellation. Ba3 (PO4)2 (aq) + 3Na2SO4 (aq) –→ 3BASO4 (s) + 2NA3PO4(aq) For the described reaction, you have a 0.200 L solution of 0.660 M Ba3(PO4)2(aq). Using the solution map from Part A as a guide, complete the following dimensional analysis that allows you to calculate he moles of BaSO4 (s) that can be formed by placing the values of each conversion factor according to whether they should appear in the numerator or denominator.

You are in the lab preparing copper solutions for the MICRO lab this week. You measure 0.1035 (±0.0001) g of copper metal and dissolve it in a few mLs of concentrated nitric acid. This solution is diluted to the mark with water in a 50.00 (±0.05) mL volumetric flask. You withdraw a 5.00 (±0.01) mL aliquot with a volumetric pipet and deliver it to a 100.00 (±0.08) mL volumetric flask. After dilution to the mark with water, calculate the concentration and the absolute error in a solution of copper in ppm (assume ppm = 1 µg/g = 1 µg/mL = 1 mg/L).
Is the final answer correct ? Or would there only be two significant figures in the final answer ?
