THE MEANING OF % IS
1 gm of substance in 100 mL of solvent.(w/v)
so you can prepare 1 % sodium citrate by dissolving 1.0 g of Sodium citrate in to 100 ml of water.
One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate.
Dissolve 30-40 g of sodium chloride in 1 L of water.
