The concentration of the final solution will be 0.2886 M.
<h3>Molar concentration</h3>
50.6 g of NaCl is dissolved in 600 mL of water.
Mole of 50.6 g NaCl = 50.6/58.44 = 0.8658 mol
Molar concentration of the oiriginal solution = 0.8658/06 = 1.4431 M
25 mL of 1.4431 M of the solution is diluted up to the 125 mL mark.
m1 = 1.4431, v1 = 25 ml, v2 = 125 mL
m2 = m1v1/v2 = 1.4431 x 25/125 = 0.2886 M
The concentration of the final solution will be 0.2886 M

Answer:
25.6 grams of ethanol in 32.5 ml of the substance.
Explanation:
The density of ethanol can be used as a conversion factor. We know that:
Ethanol is 0.789 g/ml. That becomes a conversion factor that we may write as (0.789 g/ml) and then convert either grams ethaanol or ml ethanol into the other unit. We are given volume of ethanol: 32.5 ml.
Note that when we multiply (0.789 g/ml) by (32.5 ml) the ml unit cancels, leaving just grams. That's what we want, so:
(0.789 g/ml)(32.5 ml) = 25.6 grams of ethanol in 32.5 ml of the substance.
Steam distillation is a separation process for temperature sensitive materials and it is used for purification of organic compounds.
The water vapor carries small amounts of the vaporized compounds (water and organic molecules) to the condensation flask. This is preferred technique because allows easy separation of the components by decantation or other suitable methods, because product od distilation is a two phase system<span> of water and the organic distillate.</span>
