How much pure acid must be added to 12 ounces of a 40 percent acid solution in order to produce 60 percent acid solution?
To find the amount of pure acid to add, set up an equation based on the amount of acid in the original solution and the final solution. Let x be the amount of pure acid to add. The amount of acid in the original solution is 0.4 × 12 = 4.8 ounces. The amount of acid in the final solution is 0.6 × (12 + x) = 4.8 + 0.6x ounces. Therefore, to get a 60% acid solution, you would need to add 10.67 ounces of pure acid.
If a 12 percent brine solution was mixed with a 16 percent brine solution obtaining 40ml of a 15 percent brine solution how much of the 12 percent brine solution was used in the mixture?
Let x = the amount of 12% solution. Let 40 - x = the amount of 16% solution. So we have, (0.12)x + (0.16)(40 - x) = (0.15)(40) (0.12)x + 6.4 - 0.16x = 6 -0.04x = 6 - 6.4 -0.04x = -0.4 x = -0.4/-0.04 x = 10 There are 10 ml of the 12% solution, which leaves 30 ml as the amount of 16% solution.
How many milliliter of a 20 percent and a 65 percent solutions should you mix together to make 500 milliliter of a 45 percent solution?
Let x be the amount of the 20% solution and y be the amount of the 65% solution. The total volume equation is: x + y = 500. The total amount of the solute equation is: 0.20x + 0.65y = 0.45(500). Solve these two equations to find the amounts of each solution needed.
How do you find the solubility of an element using a solubility curve?
To find the solubility of an element using a solubility curve, locate the temperature on the horizontal axis and then find the corresponding solubility value on the vertical axis. Follow the curve that represents the element to determine its solubility at the specific temperature.
When looking at 2 solutions what is the more concentrated solution?
The more concentrated solution is the one with a higher solute concentration compared to the other solution. This can be determined by comparing the amount of solute dissolved in a given amount of solvent in each solution.
How to find the volume from molarity in a solution?
To find the volume from molarity in a solution, use the formula: volume (in liters) amount of solute (in moles) / molarity (in mol/L). This equation helps determine the volume of a solution based on its molarity and the amount of solute present.
Why would you test pure water in a calorimeter to find the concentration of protein in a solution?
test the pureity of water
What is the percent acidity of the solution?
To find the percent acidity of a solution, divide the amount of acid by the total solution volume and multiply by 100. This will give you the percentage of acidity in the solution.
What are the best books with protein shakes recipes?
You can find protein shake recipes in books like that of the P90X series. They have them based on calories, flavor, and amount of protein per serving.
Where can I find food with protein?

How do you find out if citric acid forms a solution with water?
To find out if citric acid forms a solution with water, you can simply mix a small amount of citric acid into water and observe if it dissolves completely. If it does, then citric acid is soluble in water, forming a solution.
What has protein in it that you can find in your house?
Any type of meat, seed, or nut is a good source of protein. Peanut butter is actually one of the riches sources of protein available. Any endible plant is going to have some protein, but few besides nuts and seed have a significant amount.
Where do you find protein?
You find protein in rice,eggs,meats and milk.
How can I find out whether a unknown mixture has protein in it?
The most common method is the biuret test: in the presence of a copper(II) solution and NaOH the sample become violet.
What vegetables and fruit have protein?

How to find the volume when given molarity and moles?
To find the volume when given molarity and moles, use the formula: volume moles / molarity. This formula helps calculate the volume of a solution based on the amount of solute (moles) and the concentration of the solution (molarity).
