3. How would you use to make 2 liters of a 600 mM many grams (g) of NaCl NaCl solution? Show your ealeulations. AnswerSolution
Ans. Given,
Desired concentration of NaCl solution = 600 mM ; [mM = milli molar]
= 600 x 10-3 M ; [1 mM = 10-3 M]
= 0.60 M
So, we need to prepare 0.60 M solution.
Volume of solution required = 2.0 L
Now,
Number of moles of NaCl required = Molarity x volume (in Liters) of solution
= 0.60 M x 2.0 L ; [1 M = 1 mol/L]
= (0.60 mol/ L) x 2.0 L
= 1.2 mol
Mass of NaCl required = Number of required moles x molar mass of NaCl
= 1.2 mol x (58.44 g/ mol)
= 70.128 g
So, we require 70.128 g NaCl to prepare our desired solution.
