How do 0.5 mm and 2.0 M aqueous solutions of NaCl differ?
How do 0.5M and 2.0M aqueous solutions of NaCl differ? The 2.0M solution contains more moles of NaCl per volume of water than the 0.5M solution. Under what conditions might a chemist describe a solution in terms of molality?How many moles of NaCl are in 2.0 L of a 0.5 M solution?
If you know the Molecular weight of NaCl you multiply with 0.5 to get the answer. Required number of moles =2?0.25=0.5 moles.How do you make a 0.5 M solution of NaCl?
For example, if you wanted a 0.5 M solution, you would use 0.5 x 58.44 g/mol of NaCl in 1 L of solution or 29.22 g of NaCl.- Reason for 1m more concentrated: Because 1 molar solution contains 1 mole of solute in 1 litre of the solution, which includes both solute and solvent, it is more concentrated than 1 molar solution. Consequently, less than 1000 grams of water serve as the solvent mass.
