The total mass of solute and solvent is 8.76 + 84.5 = 93.26 g. Percentage of naphthalene = 8.76/93.26 x 100 = 9.39 %.

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
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.
How would I answer this question How many grams to 0.1 g of ethanol should be dissolved into 135 g of water to produce a 23 percent by mass ethanol solution?
The answer is 31,05 g ethanol.
What is meant by a 5 percent sugar solution?
Unfortunately sugar is an imprecise term. It is better to specify glucose (usually means dextrose) or sucrose or fructose etc.A 5 percent solution of one of these sugars would contain 5 grams weight dissolved in 100mL of water (or could be another solvent).Read more: What_does_a_5_percent_sugar_solution_mean
What is the percent by mass of benzene in a solution containing 14.2 g of bezene in 28.0 g of carbon tetrachloride?
If it is pure benzene and CCl4 your answer is; % Benzene = (m Benzene)/(m Total)*100 = 14.2 / (14.2 + 28) * 100 = 33.65 % If the solution is benzene and CCl4 dissolved in water or another solvent, the answer depends entirely on how much solvent you have.

What is the difference between a percent saturated solution of ammonium sulfate and percent wv solution of ammonium sulfate?
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
How many ml of a 20 percent solution should be added to 50 ml of a 40 percent solution to obtain a 25 percent solution?
150 mlLet x be the volume of 20% solution to add. The amount of "stuff" dissolved in the 20% solution plus the amount in the 40% will equal the amount of "stuff" dissolved in the 25% solution.(0.20)(X) + (0.40)(50 ml) = (0.25)(X+50ml)0.2X + 20 = 0.25X + 12.520 - 12.5 = 0.25X - 0.20X7.5 = 0.05XX = 7.5/0.05 = 150 ml
