Solutions What is the molarity of the following solutions given that: 1) 1.0 moles of potassium fluoride is dissolved to make 0.10 L of solution. 1.0 mole KF = 10. M 0.10 L soln 2) 1.0 grams of potassium fluoride is dissolved to make 0.10 L of solution. 1.0 g KF x 1 mole KF = 0.0172 mol KF 58 g KF 0.0172 mol KF = 0.17 M 0.10 L soln 3) 1.0 grams of potassium fluoride is dissolved to make 0.10 mL of solution. 1.0 g KF x 1 mole KF = 0.0172 mol KF 58 g KF 0.0172 mol KF = 170 M 1 x 10-4 L soln 4) 952 grams of ammonium carbonate are dissolved to make 1750 mL of solution. 952 g (NH4)2CO3 x 1 mole (NH4)2CO3 = 9.92 mole (NH4)2CO3 96 g (NH4)2CO3 9.92 mole (NH4)2CO3 = 5.67 M 1.75 L soln 5) 9.82 grams of lead (IV) nitrate are dissolved to make 465 mL of solution. 9.82 g Pb(NO3)4 x 1 mole Pb(NO3)4 = 0.0216 moles Pb(NO3)4 455.2 g Pb(NO3)4 0.0216 moles Pb(NO3)4 = 0.0465 M 0.0465 L soln
