What is meant by the mass mass percent concentration of a solution?
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.
What is the mass of the solution when 1 pound of salt is dissolved into 20 pounds of water?
21 Pounds.
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')
How do you prepare an aqueous solution as a percentage?
percent by mass = (mass of solute) / (mass of solute + mass of solvent) x 100% Ex: if you need a 12% by mass solution of salt then the easiest way is to get 12 g salt and 88 g of water thus the total is 100 g. 12 / (12+88) x 100% = 12%
What is a solution of 75 g of CaC1 in 100 g of water?
(75)/(100+75)x100% = 41.28% by mass
What is meant by the mass mass percent concentration of a solution?

What is the mole fraction of water in a water ethanol solution that is 57 percent water by mass?
0,98
If you have 4 grams of sand and 13 millilters of water what is the mass of the solution?
The mass is 17 g.
How is the quantity of salt affected when the salt is reclaimed from a salt-and-water solution?
The mass of salt reclaimed should be the same as the mass of salt that was put into the solution.
How do you mix 32oz of solution 1 1 ratio with water?
A 1:1 ratio can be defined in terms of volume or in terms of mass (weight). In either case, if the solution does not already contain water, a 1:1 ratio will require the same quantities of the solution and of water. The question suggests that the ratio is by mass, so add 32 ounces (mass) of water.
A sugar solution of 35.8g sugar and 125.35g of water. what is the percent by mass of the sugar and the percent by mass of the water in the solution?
add 35.8g sugar to 125.35g of water this = 100% of the solution. then divide 35.8g of sugar by the whole solution and multiply by 100 to get the percentage (35.8)/ (125.35 + 35.8)= .222 * 100= 22.2% sugar is 22.2% of the solution. Do the same for the water switch 35.8 by 125.35
What is the mass of a salt and water solution when it is left in a warm place for a long time?
A mass of salt and water solution that has been left in a warm place for a long time becomes brine, and then eventually it becomes salt, because the water evaporates.
What is the mass of the solution 17.8 grams of sodium chloride are added to 217 grams of water?
The mass is 234,8 g.

What is e boiling?
E Boiling is the measure of the energy required to vaporize the solution, converting the water at 100 degrees to steam at 100 degrees. E Boiling is calculated from values of solution mass during thepower-on portion of the run:E Boiling = (Initial Mass - Final Mass)*540*4.186,where Initial Mass is the solution mass at the start of the power-on portion of the run, and Final Mass is the solution mass at the end of the power-on portion of the run. The constant 540 is the heat of vaporization of water in calories per gram.
What is a concentration of a solution?
The concentration of a solution is basically how strong the solution is.
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 -------------------
