1550 mixture-----------------78,9 acetone
100 mixture-------------------x
x = 78,9 x 100/1559 = 5,09
The concentration of acetone is 5,o9 %.
78.9 ml/1550 ml (x100) = 5.09 = 5.00% v/v
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
As you increase the concentration of the solution, the concentration of H+ does not change. Meaning, the concentration ionized does not change. Just the original concentration increases. Since percent ionization = (concentration ionized)/(original concentration) , and the original concentration is increased, the percent ionization therefore decreases.
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
No. Everything below 0.9% of NaCl is hypotonic and every solution with concentration over 0.9% is hypertonic solution. Isotonic solution (to blood) is the one that has 0.9% of NaCl, or some other concentration of another compound.
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g

Calculating concentration of a chemical solution is a basic skill all students of chemistry must develop early in their studies. What is concentration?
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
The answer is 5,82 %.
Calculate the weight of sucrose for the desired volume and concentration of the solution.
13.6% methanol solution.
No. Everything below 0.9% of NaCl is hypotonic and every solution with concentration over 0.9% is hypertonic solution. Isotonic solution (to blood) is the one that has 0.9% of NaCl, or some other concentration of another compound.
