Web3 jan. 2024 · As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the … WebScience Chemistry Molarity Calculations. Report answers with correct units and number of sig figs please. 1. How many grams of NaCl are in 500. mL of a 1.5 M solution? 2. Calculate the molarity of the solution if 72.8g of ethanol, C2H6O, is dissolved in 2.34 L of solution? 3. What volume of 0.200 M ethanol solution contains 1.22 moles of ethanol?

WebSince the molar mass (gram formula mass of sodium chloride is 58 grams per mole ( Na = 23 g and Cl = 35 g , 23 + 35 = 58 g/mol) the mole value of the NaCl is 0.5 moles (29 g / 58 g/mol = 0.5 moles). The mass of water is 1000 grams which is converted to 1.0 kg. Molality = moles of solute / kg of solvent. Molality = 0.5 moles / 1.0 kg = 0.5 molal.
