This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution.
Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water.
90 grams + 10 grams = 100 grams (mass of total solution).
(10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.

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 do you find the mass percent mole fraction molality and molarity of a solution?
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
How many parts per million of a solute is present in a solution that is 3 percent by mass?
30,000ppm
Convert 60 percent solution to 40 percent solution?
All percentages are in mass% and all quantities are in grams (mass), be sure do not to take volumes into account because mass is 'additive', volumes are not quantitatively additable!Answer: Take whatever mass of 60 percent solution you have, multiply that mass by 20 (=60-40) and then divide that amount by 40, this is how much water to add to get an 40% solution.Example: Suppose you have 100 gram of 60% solution, then you should add:100 * (60-40)/40 = 100*0.50 = 50 gram of water; this is to be added to 100 gram of 60% solution to get (50 + 100 =) 150 gram of 40% solution.(see on top of the page to know why this calculation method is not valid for 'volumes')
A 5.0 percent glucose solution has a specific gravity of 1.06. What is the mass in g of 335.7 mL of the glucose solution?
335.7*1.06 = 355.842 grammes
How much sugar is there in 100mL of a10 percent aqueous sugar solution and what is the solvent in the solution?
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
What is meant by the concentration of a solution involving volume and mass?
Concentration is a measure of mass in a certain volume, its called m/v concentration. (Others: m/m concentration, v/v concentration)
What is a concentration of a solution?
The concentration of a solution is basically how strong the solution is.
What is the percentage by mass of salt solution prepared by dissolving 11 grams of salt in 80 grams of solution with solution?
The percent concentration is 13,75 %.
What is the percent by mass of N in CaCN2?
How is solution 1 made? What is its concentration? Need to know this to answer the question.
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
Does 14 percent sodium hypochlorite mean 14 percent sodium hypochlorite mass per weight concentration or 14 percent chlorine gas mass per weight concentration equivalent of the solution?
It means 14% of the molecules of the sodium Hypochlorite solution contain the "free-chlorine" required to actually do the desired job of the Hypochlorite. Effectively, only 14% of the mass or moles of the Hypochlorite will react.
What is the percent concentration by mass of a solution 4.2g of NaNO3 in 60 g water?
4.2 grams NaNO3/60 grams water * 100 = 7% by mass -------------------
Does the Mass mass percent concentration measures grams of solute per grams of solvent?
No, not exactly.Mass mass percent concentration measures grams of solute per 100 grams of solution (= solvent + solute)Example:58.5 g NaCl (solute) added to941.5 g H2O (solvent) gives you1000.0 g solution of 5.85% NaCl (= 100%*58.5/1000.0),which is about a 1.0 mol/L NaCl solution.
What is the mass percent of NaCl when 6.5g of NaCl dissolves with 250g of water?
This concentration of NaCl is 2,6 g NaCl/100 mL solution.
If you dissolve 5 grams of salt in 100 ml of water what is the concentration of the solution in percent?
% of solute by mass = mass of solute/mass of solution *100 =10/110 *100=100/11=9.09%
Measured in grams of solute per gram of solution?
A way of describing the concentration of solute in a compound or mixture is called Mass percentage or percent composition by mass. It can be calculated by dividing the mass of a component by the total mass of the mixture, then multiply the answer by 100%.
