How much water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
What is meant by 47 percent of NaOH solution?
This term means that 47% of the weight of this solution is sodium hydroxide.
What is the molality of 7.80 percent by weight glucose solution?
Assuming that is is a solution of glucose in water, the answer is 93%.
If you have a 300ml of a 15 percent hydrochloric acid solution in dilute the solution to 1000ml with sterile water what percent should appear on the label?
The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.
What weight of glucose is required to prepare 2 L of a 5 percent weight to volume solution?
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
How much water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
How much water must be added to 40 ml of a 25 percent by weight solution to make a 2 percent by weight solution?
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
How do you convert mass fraction to weight percent?
Multiply the mass fraction by 100.
575 milliliters of a copper sulfate solution contains 2 percent copper sulfate how many milliliters of the solution are copper sulfate?
You will have to assume that the 2 % is a volume fraction, then the volume of copper sulfate in the solution would be 11.5 milliliter(575 ml*(0.02). If it were a weight fraction, then you would have to have more information on the solution density.
How many grams in 1 percent solution?
A 1% solution normally contains 1 gram of active ingredient per 100 ml of solution (weight-volume percent) Could also be 1gm per 100 gms (weight-weight percent)- but normally weight-volume is used.
How many grams of sodium hydroxide must be dissolve in 200 g of water to produce a 4.00 percent by mass aqueous sodium hydroxide solution?
4.00% (percent) by mass (weight) means 4.00g for each 100g of solution. There are 2 x 100g of water, so 2 x 4g =8.00g of NaOH (sodium hydroxide) But, a 4% aqueous solution of NaOH should mean it's 96% (96g) water. There are 2.08333 x 96g of water, so 2.08333 x 4g = 8.33g of NaOH.

Calculate the weight of sucrose for the desired volume and concentration of the solution.
What is meant by 47 percent of NaOH solution?
This term means that 47% of the weight of this solution is sodium hydroxide.
The molecular weight of NaCl determined by studing freezing point depression of its 0.5 percent aqueous solution is 30. What the apparent degree of dissociation of NaCl is?
Theritical MM/ Observed MM = 1 + a (2-1) 58.5/30 = 1+a a = .95 or 95%
What is the molality of 7.80 percent by weight glucose solution?
Assuming that is is a solution of glucose in water, the answer is 93%.
If you have a 300ml of a 15 percent hydrochloric acid solution in dilute the solution to 1000ml with sterile water what percent should appear on the label?
The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.
