How many grams of nacl should be added to 250 grams of waterto
make a 0.40 m solution?

5.85 grams of NaCl should be added to 250 grams of water to  make a 0.40 m solution.

Explanation:

Mass of NaCl =x

Molar mass of NaCl = 58.5 g/mol

Molality of the solution = 0.40 m

Mass of the solvent = 250 g = 0.250 kg (1g = 0.001 kg)

5.85 grams of NaCl should be added to 250 grams of water to  make a 0.40 m solution.

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
