179.9 ml of 0.224 M NaNO3, 234.4mL of 0.151 M Na2SO4, and 152.4 mL of 0.110 M Ca(NO3)2 are mixed in a beaker. Calculate the molar concentration of each ion the beaker. Calculate the molar concentration of each ion in the beaker. Assume that none of the ions react with any of the other ions, and the volumes are additive
Assuming that the process is working as intended, draw and label the flowchart, do the degree-of-freedom analysis, and estimate the molar flow rate (lb-mole/h) of the humidified outlet air
