What is the meaning of percent by volume in science?
Suppose there is x% by volume of something in a mixture then it simply means out of 100 ml of that sample x ml is of that thing. ------------------------------------------------------------------- There are two common ways of indicating how much of each element or compound is contained in a mixture. They are percent by volume and percent by weight. For example, the amount of alcohol in an alcoholic beverage is measured in proof, where one proof equals one half percent alcohol by volume.
What is the difference of percent of mass and percent of volume?
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
50 percent dextrose solution and you need a 1 percent dextrose soultion. How do you figure that out?
If the percents given are by weight or mass, this is very straightforward: The ratio between the desired percentage and the initial percentage is 1/50. Therefore, a given mass of initial solution must be diluted to 50 times its original mass to obtain the desired lower concentration, or in other words, 49 parts of diluent must be mixed with each part of initial solution. If the percents involve volume measurements, it would be necessary to take into account and change in density occasioned by the dilution.
How much does a 10 pound brick weigh underwater?
That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
How do you calculate volume if given bulk density?
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
A pharmacist needs to obtain a 70 percent alcohol solution How many ounces of a 30 percent alcohol solution must be mixed with 40 ounces of an 80 percent alcohol solution to obtain 70 percent alcohol?
(Note: This answer assumes that the "ounces" specified are avoirdupois or other weight ounces and that percentages are by weight; otherwise possible volume changes on dilution must by considered.) The weight of pure alcohol in each solution is the product of the percentage and the total weight of the solution. Therefore, designating the unknown weight of 30 % alcohol as w, from the problem statement 0.30w + 0.80(40) = 0.70(w + 40), or 0.30w + 32 = 0.70w + 28, or 32 - 28 = w(0.70 - 0.30) or w = 4/0.40 = 10 ounces of 30 % alcohol.
What does 86 percent alcohol mean?
It means that either 86% of the weight is alcohol, or 86% of the volume. Volume is more standard, I believe.It means that either 86% of the weight is alcohol, or 86% of the volume.

How do make a percent sucrose solution?
To make a percent sucrose solution, dissolve a specific weight of sucrose in a specific volume of water. For example, to make a 10% sucrose solution, dissolve 10 grams of sucrose in 90 mL of water. The formula to calculate the amount of sucrose needed is: (percent sucrose/100) x volume of solution = weight of sucrose (in grams).
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.
What is the weight of 10 percent acetic acid?
The weight of 10 percent acetic acid solution would depend on the total volume of the solution. For example, if you have 100 grams of a 10 percent acetic acid solution, it would contain 10 grams of acetic acid.
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 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 determine the number of grams of an active ingredient in a solution based on the percent strength?
You can determine the number of grams of an active ingredient in a solution by multiplying the percent strength of the solution by the total weight or volume of the solution. This will give you the weight of the active ingredient present in the solution.

How do you prepare 1 percent phenolphthalein in 2000ml?
To prepare a 1% phenolphthalein solution in 2000mL, you would need to dissolve 20g of phenolphthalein in 2000mL of solvent (usually water or alcohol). This will result in a 1% solution by weight/volume. Remember to wear appropriate personal protective equipment and handle chemicals with care.
Vinegar solution has density of 1.01 grams per milliliter what is the percent by weight of CH3CO2H in vinegar?
To find the percent by weight of CH3CO2H in vinegar, you need to know the molar mass of CH3CO2H and the density of vinegar. Once you have that information, you can calculate the weight of CH3CO2H in a given volume of vinegar, and then express that weight as a percentage of the total weight of the solution.
