Question

You wish to prepare a solution that is 12% sodium chloride by mass. How much sodium chloride is necessary to prepare 2.0 kg of this solution?

science chemistry

Answer 1

Answer #1

12% NaCl = 12 g NaCl in 100 g (mL) water. ........... 112 g solution.

1 g solution contains 12/112 grams of NaCl (= 0.107 g)

2000 g solution contains (12/112) X 2000 grams of sodium chloride (214.2857 g NaCl)

Answer is 214.2857g
