Web2 sep. 2024 · 4. Divide the number of moles by the number of liters. Now that you have the number of liters, you can divide the number of moles of solute by this value in order to find the molarity of the solution. [10] Example problem: molarity = moles of solute / liters of solution = 1.2 mol CaCl 2 / 2.905 L = 0.413080895. 5. Web12. how many moles are in 160 grams Ca?With solution po♀️ Answer: 160 g of Ca × 1 mole of Ca / 40.078 g of Ca = 160 g mole / 40. 078 g of Ca = * cancel out the g = 3.992 …

Web22 jun. 2024 · 1.5 moles. 2 Answers By Expert Tutors This means 1.5 molar, which means 1.5 moles of sodium chloride (NaCl) per 1 liter of solution. Since the question asks to make 100 ml, not 1 liter, we need to make that adjustment. 1.5 moles = 1.5 moles x 58.44 g/mol = 87.66 g. This is the mass needed to make 1 liter (1000 ml). Web22 mei 2024 · Molar Volume of Gases. One of the most practical results of this law is the molar volume of a gases, V m, which is about:. V m = 22.4 dm 3 / mol. It means, at standard temperature (273.15 K, 0°C) and standard atmospheric pressure (101.325 kPa) the molar volume is the same for all ideal gases. Note that, it is under the ideal gas assumption. tathra life saving club
