Step 2: Identify the Given ValuesFrom the question, we know:- Molality (m) = 1.55 m- Mass of solvent (water) = 2 kg Step 3: Calculate the Number of Moles of Ethyl AlcoholUsing the formula for molality, we can rearrange it to find the number of moles of solute (ethyl alcohol):Numb...
Imagine the lab scenario with some arbitrary values: You have a beaker with a measured 10mL of HCl (unknown Molarity) which you weigh the solution as 10g. You need to find out the mass of the solvent. Ultimately, I need to determine the Molarity of the solution but I need themass of ...
Divide the number of moles by the volume of solution in liters (L). If, for instance, the solution is 1.5 L — 1.32 ÷ 1.5 = 0.88. This is the solution's particle concentration, measured in molarity (M), or moles per liter.Cite This Article MLA Menezes, Ryan. "How To Calculate ...
Divide the mass of the solute by the molar mass to get the number of moles of solute. In this case, work out 200 ÷ 58 = 3.4483 moles of solute.Calculating Molarity When you know moles of solute, you can work out molarity (M), the concentration of a solution expressed as the number...
