In order to find the number of moles of potassium chloride, your solute, use the compound's molar mass, which as you know tells you the mass of one mole of potassium chlorideMolar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules. One mole contains exactly 6.022 ×10 23 particles (Avogadro's number) Steps to calculate molar massThere are 4 easy steps to find the molar mass of KCl based on its chemical formula. 1. Count ...Oct 17, 2018 · Explanation of how to find the molar mass of KCl: Potassium chloride. A few things to consider when finding the molar mass for KCl: - make sure you have the correct chemical formula. -... (The molar mass of KCl = 74.55 g/mol and the molar mass of H2O is 18.02 g/mol.) A solution contains 4.46 g KCl in 178 mL of solution. The density of the KCl solution is 1.11 g / ml. What is the percent (m / m) for the potassium chloride solution? An aqueous solution that is 26% KCl by mass has a density of 1.09 g/mL.The molar mass will be equal to: (1 atom x 56 grams/mole Fe) + (2 atoms x 35.5 grams/mole of chlorine) = 127 grams/mole of iron (II) chloride. For other compounds, this might get a little bit more complicated. For example, take the example of zinc nitrate, or Zn (NO 3) 2. In this compound, we have one atom of zinc, two atoms of nitrogen (one ...To find the mass of one mole of potassium, just convert the atomic mass of potassium to grams. One mole of potassium has a mass of 39.10 grams. One mole of chlorine has a mass of 35.45 grams. Adding the mass of these two atoms gives a total of 74.55 grams as the molar mass of potassium chloride.The molar mass of KCl is 74.5513 grams/mol. Its density in the solid, crystalline form is 1.984 grams per cubic centimetre. The melting and boiling points of potassium chloride are 1040 K and 1690 K respectively. At 0 o C, 20 o C, and 100 o C, the solubility of KCl in water corresponds to 217.1 g/L, 253.9 g/L, and 360.5 g/L respectively. The oral dose of 10% potassium chloride elixir (Kay Ciel) required to reverse thiazide-induced hypokalemia was determined in 15 patients with essential hypertension who were taking Esidrix (hydrochlorothiazide) in a dose of 50 mg. twice daily.Each patient had maintained a serum potassium concentration of at least 0.5 meq./l. less than duplicate ….
