WebAssume the density of the solution is 1.03 g/mL. What is the concentration (in molality) of an aqueous solution of NaCl made by adding 4.56 g of NaCl to enough water to give 20.0 mL of solution. Assume the density of the solution is 1.03 g/mL. Expert Answer 1st step All steps Final answer Step 1/2 WebMolarity is the concentration of a solution. It is also known as molar concentration. Molarity is the number of moles of solute per litre of solution. It is denoted by the symbol M. The formula is given below: M o l a r i t y = m o l e s o f s o l u t e l i t e r s o f s o l u t i o n.
Relation Between Molarity And Molality: Know Relation …
WebApr 27, 2016 · Use the density of the solution to get the total volume of the solution. Then use the weight percent of solute to determine the amount of substance of the solute. Use the amount of substance of the solute divided by the volume to get molarity. Molarity is relevant to our concept of chemistry and kinetics of reactions. WebJul 4, 2024 · A The molarity is the number of moles of acetic acid per liter of solution. We can calculate the number of moles of acetic acid as its mass divided by its molar mass. The volume of the solution equals its mass divided by its density. The calculations follow: molesCH3CO2H = 3.78 g CH3CO2H 60.05 g / mol = 0.0629 mol def in physical design
