determine the mass percent of a 100 mg. salt solution which contains 20g. salt?
Mass solution=100g Mass solution=20g Mass Mass % = (mass Of solute/mass Of solution ) x 100. =(20/100)x100 =1/5 x 100. =100/5 =20%
If you have 1000 gram of a 10 -percent solution of sugar water how much sugar is dissolved in the solution?
The mass of sugar is 100 g.

A chemist is making 200 L of a solution that is 62 percent acid He is mixing an 80 percent acid solution with a 30 percent acid solution How much of the 80 percent acid solution will he use?
The chemist will use 100 liters of the 80% acid solution and 100 liters of the 30% acid solution to make a 200-liter solution that is 62% acid. The amount of acid in the 80% solution will be 0.8 * 100 = 80 liters, and in the 30% solution, it will be 0.3 * 100 = 30 liters.
How many litres of 12 percent sodium hypochlorite solution are needed to make 100 Litre of 2 percent sodium hypochlorite solution?
To make a 2% sodium hypochlorite solution from a 12% solution, you can set up the equation: 12% solution * x litres = 2% solution * 100 litres Solving for x, you get: x = (2% solution * 100 litres) / 12% = 16.67 litres Therefore, you would need 16.67 litres of the 12% sodium hypochlorite solution to make 100 litres of a 2% solution.
What is the concentration of solution which contains 16g of urea in 120g of solution?
The concentration of the solution is calculated by dividing the mass of solute (urea) by the total mass of the solution and then multiplying by 100%. In this case, the concentration of the solution containing 16g of urea in 120g of solution would be 16g / 120g * 100% = 13.3%.
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%

How many grams of thimerosal are required to make 50 g of 100 percent solution?
I need help with this! the problem says "Thimerosal is an organic compound (gram-molecultar mass = 404.8 g/mol). A .100% solution of thimerosal is sometimes used as an antiseptic. Assume that this solution has a density of 1.00 g/mL." I need help with these two: What mass of thimerosal must be mixed with 25.0 g of water to make a .100% solution? What volume of 0.100% solution contains 0.750 g of thimerosal?
How do you prepare standard 0.1 N 100 ml Na2CO3 solution?
To prepare a 0.1 N 100 ml Na2CO3 solution, dissolve 5.3 grams of Na2CO3 in water and dilute to 100 ml. This will give you a solution with a concentration of 0.1 normal (N) for the 100 ml volume.
