Question

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 within 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 0.420 L solution of 0.840 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 the 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. Drag the appropriate values to their respective targets.
