It will be 11.5 gm od Na metal
The mass of sodium hypochlorite in 2,5 kg solution is 131,25 g.Sodium chloride is only the product of a decomposition.
Balanced equation first. 2Na + Cl2 -> 2NaCl 35 grams NaCl (1 mole NaCl/58.44 grams )( 1 mole Cl2/2 mole NaCl )( 70.9 grams Cl2/1 mole Cl2) = 21 grams of Cl2 needed
The mass is 234,8 g.
Calculate the mass (in grams) of sodium sulfide that is needed to make 360ml of a 0.50 mol/L solution
I suppose that this solution doesn't exist.
98g
1.17 grams :)
The sodium chloride mass needed is 292,2 g
262 - 266
262 - 266
600 mL of 0,9 % sodium chloride: 6 x 0,9 = 5,4 grams NaCl

The needed mass is 0,0584 g.
The needed mass of sodium chloride is 29,22 g.
One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate.
