Simplest experiment is to take this water solution having undissolved solids in a hundred ml graduated cylinder upto its mark(100ml). Allow to stand for about half an hour, then note the level of undissolved solids at the bottom of the cylinder. Read that level as percent of solids in the water by weight.
To determine percentage of solids by weight:
Find the weight of water+undissolved solids
Filter water solution through a filter paper.
Find the weight of filtered water.
Find the weight of dried solids.
Percentage of undissolved solids = wt of undissolved solids divided by total weight of water and solids multiplied by 100

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
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 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
