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.
What is meant by 47 percent of NaOH solution?
This term means that 47% of the weight of this solution is sodium hydroxide.
How would you make a 5M solution of glucose?
The molecular weight of glucose is 180. Let's say that you intend to make 100 ml of 5M solution. Here is the formula that can help you out every time you are dealing with molarity. (X, which is the desired weight divided by the molecular weight) X (1000/100, which is the desired volume) = 5, which is the desired molarity. So, X/180 X 1000/100 = 5; then X = 90. You need 90 g of glucose to make a 5 M of 100 ml solution of glucose. Hope this is clear, Samba.
What is the molarity of an aqueous solution containing 40 g of glucose in 1.5 l of solution?
You need to convert to g/litres first. 40/1.5 is 26.6667g. The molecular weight of glucose is 180.156. 26.66667/180.156 is 0.148 molar.
What is another way to express the concentration of a glucose solution that is 0.01 percent by weight?
100ppb

its 100 ppm
Formula for molality?
== Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) ==
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 mean by weight by weight?
"weight by weight" is term, we use in chemistry. it is similar to terms like molarity, molality, normality etc. "weight by weight" defines the ratio of solute vs solvent in solution or mixture specially when we deals with solid in solid mixture or solution
What is the molality of a substance?
Molality is the number of moles of a solute divided by the weight of the solvent in kilograms.
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 do make a percent sucrose solution?
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.
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
