AI Thread Summary
To find the molarity of the resulting solutions, first calculate the number of moles of HNO3 and HCl in each mixture using the formula: moles = concentration (M) × volume (L). For the first mixture, convert 553.6 mL of water to liters and add it to the volume of HNO3 to find the total volume, then divide the moles of HNO3 by this total volume. In the second mixture, combine the volumes of both HCl solutions, convert to liters, and calculate the total moles of HCl before dividing by the total volume. The final molarity of each solution can be determined by these calculations. Accurate conversions and proper volume addition are crucial for correct results.

What is the molarity of each resulting solution when the following mixtures are prepared?

553.6 mL H2O is added to 20.0 mL 4.79 M HNO3

20.8 mL 1.75 M HCl is added to 80.0 mL 0.534 M HCl

Come on! This isn't very hard if you give a moment's thought...

1 M = 1 mol per dm^3

1 dm^3 = 1000 ml

Calculate the number of moles in each case, making the appropiate conversions, and divide by the total volume of solvent.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
