Answer:
Dissolve 11.7 grams of NaCl in 500 ml of water and it will give 0.4 M NaCl solution.
Explanation:
As we know that
Thus the number of moles of NaCl required to form 0.4 molar solution are
the volume given is 500 ml
= 500/1000 liter = 0.5 liter
putting the values
We also know that one mole of NaCl = 58.5 grams thus 0.2 moles
= 58.5 × 0.2 = 11.7 grams
THUS dissolve 11.7 grams of NaCl in 500 ml of water and it will give 0.4 M NaCl solution.
