How does the molarity change if the volume is constant but more solute is added? Molarity (M) = moles solute liter solution 1. Select cobalt(II) nitrate from the pull-down menu, and select "show values". Adjust the solute and solvent amounts and record the results in the table below. Hitting the reset button will return the solute and solution volume sliders to 0.500 moles and 0.500 L, respectively. Complete the table. Cobalt(11) nitrate Solute Amount Solution Volume Molarity 0.500 mol 0.500...

3. Concentration is a measure of the amount of solute dissolved in a given amount of solution. a. (5 pts) How many grams of NH4CI are contained in 200 mL of a 6.20% w/v NH4CI solution. b. (5 pts) What is the molarity of 975 mL of a solution containing 23.83 g of MgCl2? c. (Bonus, +6 pts) Calculate the molarity of a solution prepared by diluting 0.100L of 2.10 M KOH to a final volume of 0.420 L.

Molarity is a concentration term that relates moles of solute and total volume. We use the symbol M for Molarity and it means moles/L. If I put 1.000 mole of a solute like NaOH(s) into a 1.000 L volumetric flask and add water until the total volume is 1.000L, I have created a 1.000M solution. Anytime I use that solution, I can calculate the moles of NaOH in any volume of that solution. An example is if I have 0.320...
Concentration is the amount of solute dissolved in a certain amount of solution: concentration of a solution=amount of soluteamount of solution Solution concentrations are usually given as one of the following: Mass percent (m/m)—the mass of the solute in grams for exactly 100 g of solution Volume percent (v/v)—the volume of solute in exactly 100 mL of solution Mass/volume percent (m/v)—the mass of solute in grams for exactly 100 mL of solution Molarity (M)—the number of moles of solute in...
