It is a white crystalline solid. It is edible, commonly used as a salt substitute, but it has a sharp, biting aftertaste (which is often described as metallic) that many people find unpleasant. ... It has a molar mass of 74.55. KCl's solubility in water is 28 g/100 mL at 0 ˚C and 56.7 g/mL at ...The molar mass of Fe2O3, which is the chemical formula for iron(III) oxide, is 159.68 grams per mole. The molar mass is determined by adding together the atomic weight of each atom...Calculate the molecular mass of the following:KCl (Potassium Chloride)SUBSCRIBE if you'd like to help us out!https://www.youtube.com/channel/UC2C34WdYMOm47Pk...This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: What mass of KCl (molar mass = 74.55 g/mol) must be added to 1.0 L of 0.0180 M Pb2+ (aq) to initiate precipitation of PbCl2 (s)? The Ksp of PbCl2 is 1.7 ´ 10.The molar mass and molecular weight of 2 KCl is 149.103. Edit Elemental Percent Composition. Convert 2KCl From Moles to Grams. Moles mol. Convert to Grams and Molecules. Potassium chloride (KCl) has a molar mass of 74.551 g/mol. Calculate the mass in grams of KCl required to prepare 50.00 mL of a 0.300 mol/L aqueous solution of KCl. Report your answer to the correct number of significant figures. There are 2 steps to solve this one.The molar amount of a substance may be calculated by dividing its mass (g) by its molar mass (g/mol): The factor-label method supports this mathematical approach since the unit “g” cancels and the answer has units of “mol:”. 4.7 g K ⎛⎝ mol K 39.10 g K ⎞⎠ = 0.12mol K 4.7 g K ( mol K 39.10 g K) = 0.12 mol K..
