Answer:
60 g/L is the final concentration of NaI solution .
Explanation:
Molarity of NaI solution before evaporation =
Volume of NaI solution before evaporation =
Molarity of NaI solution after evaporation =
Volume of NaI solution after evaporation =
( dilution)
Molar mass of NaI = 150 g/mol
Concentration of NaI after evaporation :
0.4 M × 150 g/mol = 60 g/L
60 g/L is the final concentration of NaI solution .
