Web24 jun. 2016 · 14.2g ⋅ 1 mole KCl 74.55g = 0.1905 moles KCl Now, molarity is simply a measure of a solution's concentration in terms of how many moles of solute it contains per liter of solution. This means that in order to find a solution's molarity, you essentially must figure out how many moles of solute you have in 1 L of solution. WebKCl molecular weight Molar mass of KCl = 74.5513 g/mol This compound is also known as Potassium Chloride. Convert grams KCl to moles or moles KCl to grams Molecular … WebNow, using the above formula we can easily calculate the number of moles of Potassium chloride and we will get: ⇒ m o l e s = 27.5 77.55. ⇒ m o l e s = 0.354 m o l. Therefore, … 48研究所
