Calculate the volume and mass required to make 0.1M solutions of Ammonium Chloride (53.49gmol) and Ammonia (1.0M) Molarity: The molarity is always defined as the number of moles of solute that are dissolved in 1 liter of the solvent. If 1 mole of...
Calculate the molar concentration of {eq}I^- {/eq} in a saturated solution of {eq}PbI_2 {/eq} containing {eq}\left [ Pb^{2+} \right ] = 3.75 \times 10^{-4} {/eq} M. (The {eq}K_{sp} {/eq} for {eq}Pb...
Calculate the mass of Na2S required to make 340 grams of 9% Na2S solution. Mass Percent for Solutions: In chemistry we deal with various homogeneous mixtures, which have a uniform composition containing two or more different substances. A common example is a simple solution contai...
The washed and dried precipitate has mass 0.5571 g.What was the wt% of AgNO3 in the original sample?I tried to solve this using (weight precipitate)*(gravimetric factor)(100) / weight of sample but i got the wrong answer!? can someone please shed some light on this for me !?
Assuming 100% dissociation, calculate the freezing point and boiling point of a solution with 98.4 g of AgNO3 in 1.00 kg of water. Calculate the freezing point and boiling point of the 4.0% KCl by mass (in water) solution, assuming complete dissociation. ...
Molar Solubility This is the number of moles of a solute that can dissolve in a solution before saturation is achieved. The units for molar solubility is moles per liter. It can be calculated using the solubility constant. Answer and Explanation:1 ...
