- In the process of solving, it was changed to Kgmolecule-1 after adding Avogadro number. However, in the process of obtaining the value of frequency, the unit of the value of the micro was changed to kg. What is the reason?In a certain oxide of nitrogen in g/L at multiple pressures at 0 °C, different density results were obtained. Determine the Molecular Weight (MW) of the substance and the atomic weight of Nitrogen. Pressure Density 1 atm 1.9804 2/3 atm 1.3164 ½ atm 0.9861 1/3 atm 0.6565In Part B, you used a similar procedure to that of Part A to determine the mass percent of CaCO3 in an antacid tablet. The commercially accepted range of CaCO3 in an antacid tablet is 25–35% by mass. Miranda obtained the data below from her Part B trial: TRIAL PRESSURE (torr) MASS OF TABLET (g) TEMPERATURE (°C) VOLUME CO2 RECOVERED (mL) 1 750.5 0.5702 21.3 69.6 2 750.5 0.5622 21.2 68.2 Miranda determined her average % Recovery of CO2 to be 65.0% from Part A. Based on her data collected from Part A, was the average percent mass of CaCO3 in her antacid tablet within the commercially accepted range? Yes, her mass percent does fall within the commercially accepted range. No, her mass percent does not fall within the commercially accepted range.
