A 20.0-g sample of sugar is dissolved in 59.8 g of water. What is the concentration of the solution?
25 percent by mass
1g of a drug is dissolved in 2.5mL of solution what is the percentage strength of the solution ww How do you calculate percent ww when 1g of drug is dissolved in 2.5mL of solution?
40%
A solution contains 1.20 g of CaCl2 and 240 mL of solution what is the percent w-v concentration of the solution?
W-V percent concentration g/mL = 1.20g/240mL = 0.005 g/mL percent
How can you express the concentration of a substance mathematically?
In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water). For example: - 1 mole of sodium chloride = 58 grams - If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride. - If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.
What is the concentration as percent of a solution which contains 160 g of solute in 2.75L of solution?
The answer is 5,82 %.

A solution is saturated with dissolved minerals - what will happen if 50 percent of the water in the solution evaporated?
50 percent of the dissolved minerals will condense out of solution by crystallization.
If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
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.
Why does the percent ionization of acetic acid increase as the concentration of the solution decreases?
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 you have a cell with water concentration of 90 percent and solute concentration of 10 percent and you place it into a solution that is 80 percent water concentration and 20 percent solute concentra?
