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
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?
To find the percent by mass of sugar: Mass of sugar = 35.8g Total mass of solution = 35.8g (sugar) + 125.35g (water) = 161.15g Percent by mass of sugar = (mass of sugar / total mass of solution) * 100 To find the percent by mass of water: Mass of water = 125.35g Total mass of solution = 161.15g (as calculated above) Percent by mass of water = (mass of water / total mass of solution) * 100
What is the mass of the solution 17.8 grams of sodium chloride are added to 217 grams of water?
The mass of the solution would be the sum of the mass of the sodium chloride and the mass of water. So, the mass of the solution would be 17.8 grams (NaCl) + 217 grams (water) = 234.8 grams.
What mass of water must be added to 255.0g NaCl to make a 15.00 percent by mass aqueous solution?
To make a 15.00% by mass aqueous solution with NaCl, the mass of NaCl is 255.0g. This means that 15.00g of NaCl is present in every 100.00g of solution. To find the mass of water needed, first calculate the mass of NaCl in the final solution, then subtract this amount from the total mass of the solution (water + NaCl).
How do you determine the mass of salt in a solution?
To determine the mass of salt in a solution, you first need to measure the total mass of the solution. Then, you can use techniques like evaporation or filtration to separate the salt from the solution and measure the remaining mass of the solution. The difference in mass between the total solution mass and the remaining solution mass will give you the mass of the salt in the solution.
What ids the total mass of the solution when 5 gramme of salt desolved in 100 gramme of water?
The total mass of the solution is 105 grams, which is the sum of the mass of the salt (5 grams) and the mass of the water (100 grams). The mass of the solute (salt) and the solvent (water) are additive in a solution.
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.
How much water must be added to 425 g of formaldehyde to prepare a 40.0 percent by mass solution of formaldehyde?
To calculate the amount of water needed, first determine the mass of formaldehyde in the final solution. Since the solution is 40.0% formaldehyde by mass, the mass of formaldehyde is 40.0% of the final solution mass. Subtract the mass of formaldehyde in 425 g from this value to find the mass of water needed to prepare the solution.
What is the percent concentration by mass of a solution 4.2g of NaNO3 in 60 g water?
The total mass of the solution is 4.2g NaNO3 + 60g water = 64.2g. The percent concentration by mass of the NaNO3 in the solution is (4.2g / 64.2g) * 100% = 6.54%.
What is the mole fraction of water in a water ethanol solution that is 57 percent water by mass?
To calculate the mole fraction of water in the solution, we first need to determine the moles of water and ethanol present. Given that the solution is 57% water by mass, we can assume the remaining 43% is ethanol. From there, we can convert the mass percentages to moles using the molar masses of water and ethanol, and finally, calculate the mole fraction of water by dividing the moles of water by the total moles of the solution.
Salinity is the ratio of the masses of what two materials?
Salinity is the ratio of the mass of salt to the mass of water in a solution or body of water.
What is the percent by mass of the solute sodium hypochlorite is 5.24 percent you have a 2500.0 grams of bleach solution. How many grams of NaCl are in the solution?
If the percent by mass of sodium hypochlorite (NaClO) in the bleach solution is 5.24%, then 100% - 5.24% = 94.76% is the water weight. For a 2500.0g solution, the mass of NaClO is 5.24% of 2500g = 131g. Since the remaining mass is water, the mass of NaCl (sodium chloride) in the solution would be zero.
If you have 4 grams of sand and 13 millilters of water what is the mass of the solution?
The mass is 17 g.
