Which solution listed below yields the highest molar concentration? 121.45 g of KOH in 75.0 mL 23.49 g of NH4OH in 125.0 mL 217.5 g of LiNO3 in 2.00 L 15.25 g of Pb(C2H3O2)2 in 65.0 mL

The answer to your question is KOH (28.9 M)

Explanation:

Data

a) 121.45 g of KOH vol 75 ml

Molar mass = 39 + 16 + 1 = 56 g

                       56g 1 mol

                    121.45 g  x

                       x = (121.45 x 1)/56

                       x = 2.169 g

Molarity = 2.169 / 0.075

Molarity = 28.9 M

b) 23.49 g of NH₄OH vol 125 ml

Molar mass = 14 + 5 + 16 = 35 g

                      35 g 1 mol

                    23.49 g x

                      x = 0.67 moles

Molarity = 0.67 / 0.125

Molarity = 5.4 M                        

c) 217.5 g of LiNO₃ in 2L

Molar mass = 7 + 14 + 48 = 69 g

                       69 g 1 mol

                    217.5 g x

                      x = 3.15 moles

Molarity = 3.15 / 2

Molarity = 1.57

d) 15.25 g of Pb(C₂H₃O₂)₂ in 65 ml

Molar mass = 207 + 56 + 6 + 64 = 333 g

                  333 g 1 mol

                   15.25 g x

                   x = 0.046 moles

Molarity = 0.046 / 0.065

Molarity = 0.71

increased stability in the completion of fluorine's outer shell.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
