The mole fraction of HCl is 0.34.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
This term means that 47% of the weight of this solution is sodium hydroxide.
Assuming that is is a solution of glucose in water, the answer is 93%.
The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.

Multiply the mass fraction by 100.
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.
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.
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.
This term means that 47% of the weight of this solution is sodium hydroxide.
Theritical MM/ Observed MM = 1 + a (2-1) 58.5/30 = 1+a a = .95 or 95%
Assuming that is is a solution of glucose in water, the answer is 93%.
The concentration of the diluted solution will be 15(300/1000) = 4.5 %, if the percent is expressed on a weight/volume basis.
