0 5 l na cl Sodium chloride so di m kl ra d 8 commonly known as edible salt is an ionic compound with the chemical formula NaCl representing a 1 1 ratio of sodium and chlorine ions It is transparent or translucent brittle hygroscopic and occurs as the mineral halite In its edible form it is commonly used as a condiment and food preservative
How do you calculate the mass of NaCl required to prepare 0 5 liters of a 2 5 molar solution of NaCl Here s how you can do that Your starting point here will be the definition of molarity As you know molarity is defined as the A 2 5 M solution is 2 5 moles per liter Molarity is just the number of moles per liter Therefore 0 5 L would contain 1 25 mol Hence you would need 1 25 58 44 g 73 g

Thus each mole of NaCl becomes two osmoles in solution one mole of Na and one mole of Cl A solution of 1 mol L NaCl has an osmolarity of 2 Osmol L A solution of 1 mol L CaCl2 has an osmolarity of 3 Osmol L 1 mol Ca2 and 2 mol Cl EXAMPLE 1 Calculate the osmolarity of blood The concentrations of solutes are Example Determine the mole fraction of NaCl in a solution in which 0 10 moles of the salt is dissolved in 100 grams of water The moles of NaCl are provided but you still need the number of moles of water H 2 O Start by calculating the number of moles in one gram of water using periodic table data for hydrogen and oxygen
One mole of sodium Na is 22 99 g and 1 mole of chlorine is 35 45 g For sodium chloride NaCl they are in a ratio of 1 1 so the molar mass of NaCl is 22 99 35 45 58 44 g mol For a compound like water H 2 O 1 mole of hydrogen H is 1 008 g mol and 1 To calculate the number of moles of NaCl required we can use the formula moles concentration N x volume L In this case the concentration is 1N and the volume is 0 5 L Therefore the number of moles of NaCl required is 1N x 0 5 L 0 5 moles
