WebAn unknown mass of sodium chloride (NaCl) salt is placed in a beaker and distilled water is added until the total volume is 250 mL. If the concentration of chloride ion (Cl-) is later found to be 0.020 molar (M), how much sodium chloride (NaCl) salt was added to the beaker? the Gram Molecular Weight (GMW) of Na= 23 g/mol, and the GMW of Cl is ... Webgrams of solute = (wt% solution) x (ml of water) ÷ (100 – wt% solution) As an example, to make 100 ml of 10% NaCl (table salt) solution, use the previous formula to find out how much NaCl you need: grams of NaCl = (10) x (100) ÷ (100 – 10) = 11.1 g. Now you can make your solution: dissolve 11.1 g NaCl in 100 ml of water.
