Percent by Volume of Solute in Solvent = Volume Solute/ (Volume Solvent + Volume Solute) * 100% = 48/ 192 = 25%
50 percent of the dissolved minerals will condense out of solution by crystallization.
Add 10 parts water to 90 parts 100% ethanol.
Bioc 4025? Just a guess. Definition of % Saturation: The amount of a substance that is dissolved in a solution compared to the amount that could be dissolved in it. % w/v Solution: This is in terms of weight (g) per volume (mL). 2% for example is 2 g per 100 mL. gl
The cell and the solution will reach equilibrium when they each contain 40 percent water. This equilibrium is achieved through osmosis.
So as not to 'waste' too much ethanol. To use 95 % ethanol allows some ethanol to be saved!
The answer is 31,05 g ethanol.
50 percent of the dissolved minerals will condense out of solution by crystallization.
20%
10% of 6L is 600 ml. 6000 / 100 * 10 = 600 ml.
40%
50% alcohol.
1 liter exactly equals 1000 cubic centimeters (abbreviated cc, or cm3). A 6.8 percent solution means that of those 1000 cc's, 68cc's are of ethanol ((6.8/100) x 1000) Assuming pure ethanol, which it most likely is for a school problem, Wikipedia states that the density is: 0.789g/cm3 (0.789g/cc) so, 68 x 0.789 = 53.652 grams.

the solution in the balloon is hypertonic relative to the solution in the breaker. is this true
I've never tried it...but I would bet the answer is yes as they are both organic compounds.
0,98
This solution contain 5 g NaCl dissolved in water.
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
