Feb 01, 2021 · Note: 1 cm3 = 1 ml Example: Convert 0.88 M NaCl to molality. You want to convert 0.88 moles NaCl/liter solution to moles NaCl/kg of water. 0.88 M NaCl = 5% NaCl by mass has a density of 1.034 g/ml. Here is how to use the density: Convert liter of solution to g of solution: 1 liter solution = 1000 ml (1.034 g/ml) = 1034 g solution

The reverse procedure, converting solute density into a molarity solution, is not difficult. Convert the density of the solute into grams/liter, then divide the result from the molecular mass of the solute. For example, consider a solution where sodium chloride density is 0.036 g/ml. Multiply from 103 to convert to g/l = 36 g/l.

2) To use the molarity equation, you need to convert grams of sodium chloride to moles of sodium chloride before you can use the molarity equation. Because you have 0.0085 moles of NaCl in this solution, the total concentration is 0.17 M. 3) To use the molarity equation, you need to convert grams of NaCl to moles and mL of solution to liters.

molarity: Summary • Always distinguish between amount of substance in moles (grams) and concentration of substance in mol/l (g/l) • For conversion from mass to molarity divide the mass (g or g/l) with molar mass (relative AW/MW/FW) • For conversion from molarity to mass multiply the molarity (mol or mol/l) with molar mass (relative AW/MW/FW)
