How would you prepare 200 ml of 03 M NaCl NaCl MW 5844 a Mi

How would you prepare 200 ml of 0.3 M NaCl? (NaCl MW = 58.44)

a. Mix 17.53 grams of NaCl and fill with water up to 200mL

b. Mix 17.53 grams of NaCl and fill with water up to 1L

c. Mix 3.51 grams of NaCl and fill with water up to 200mL

d. Mix 58.44 grams of NaCl and fill with water up to 200mL

Answer:

c. Mix 3.51 grams of NaCl and fill with water up to 200mL

[Volume in Liters x Concentration x Molecular Weight)= 0.2 L x 0.3 moles/L x 58.44 g/mole = 3.5 g NaCl dissolved in/brought up to 200 ml water
