A chemistry teacher mixes 50.0 mL of 0.400 mol/L lead (II) nitrate, Pb(NO3)2(aq) solution with 300.0 mL of 0.220 mol/L potassium iodide, KI(aq) solution. The balanced chemical equation is provided below.    Pb(NO3)2(aq) + 2KI(aq) → 2KNO3(aq) + PbI2(s) Calculate the mass of precipitate formed in this reaction.

Sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 539 g NaOH(s)539 g NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq)NaOH(aq) solution.

The following chemical reaction takes place in aqueous solution: 2 AgF(aq)+ (NH4) CO3(aq) → Ag₂CO3(s)+2 NHÂF(aq) 2 Write the net ionic equation for this reaction.

You are carrying out an experiment to determine the MW of a solid acid with the generic formula H3A. You weigh out 0.362 g of the solid acid in a weigh boat and transfer it to a 125 mL Erlenmeyer flask. After dissolving the acid in 25 mL of distilled water, you add 22.51 mL of 0.343 M Sr(OH)2 (aq) solution with a buret until your indicator changes color at the equivalence point. What is the molar mass of the solid acid in units of g/mole? Enter your answer with at least 4 significant digits (Canvas sometimes truncates zeros so assume that all numbers in this question have at least 4 sig figs (ie if Canvas tells you there are 12.3 mL assume 12.30 mL). This question will require precision so don't round any numbers until your final answer.
