  2. Molar mass for Nacl= 58.44g/mol Volume=250ml or 0.250Litre molarity=0.4M °grams of NaCl required=Molarity × Volume in litre × Molar mass of NaCl=0.4M×0.250L×58.44g/mol=5.844g. There for 5.844g of NaCl is required to prepare 500ml of 0.4M solution NaCl. Weigh 5.844g of NaCl powder and dissolve in 500ml of Distilled water. BY BELLO LAWAL DANCHADI (STUDY HARD) FROM UDUSOK.
