- Module Code & Title: CHM9011M Chromatography and Sep Sciences Section 1: Purpose Clarity of Purpose ): Clearly states the purpose of the SOP. Relevance to Task : Demonstrates the importance and relevance of the procedure. Alignment with Goals ): Shows how the procedure aligns with organisational goals.The %purity of a powdered crude sample of Na2CO3 containing only inert impurities is to be determined by reacting 225.0 mg of the crude sample to 10.0 mL of 3.00 M HCl solution, and bubbling the resulting CO2(g) product in water that is at exactly 29 °C. After the reaction has completed, the level of the liquid inside the eudiometer rests 4.30 cm above the water level in the beaker. The graduation on the eudiometer indicates that the trapped gas is 44.37 mL. The experiment was done under a barometric pressure of 755.2 torr. a. How many moles of CO2 were collected? b.
