How many liters of water are needed to make 6.3 M solution of NaCl made with 5,128 grams of Na Cl (molar mass = 58)?

0.014 Liters needed

Explanation:

Given 5.128 grams NaCl + ?Water Solvent => 6.3M solution

Solution Concentration = moles solute/liter solution = Molarity (M)

=> Molarity (M) = 6.3M = (5.128g NaCl/58g·mole⁻¹) / Volume of Sol'n (L)

∴ Vol of Solution = Vol of Water Solvent needed

= (5.128g NaCl/58g·mole⁻¹) / 6.3M

= 0.0884 mole NaCl / 6.3 mol/L = 0.014 Liters water solvent.

Method of Mixing:

Transfer 5.128g NaCl into mixing container and add solvent water up to but not to exceed 0.014 Liters (=14 ml) total volume. Mix till homogeneous.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
