Calculate the mass of solute of hydrogen peroxide in a 35% solution if 450 ml of solution is being used
I assume this is 35% w/v from the wording in the problem.
35% w/v means 35 g H2O2/100 mL soln. In 450 mL we will have
35 g x 450 mL/100 mL = ?
To calculate the mass of solute (hydrogen peroxide) in a 35% solution, you'll need to know the density of the solution, which is typically provided.
Assuming the density of the solution is 1.1 g/ml, you can use the following steps:
Step 1: Convert the volume of the solution from milliliters (ml) to grams (g):
Mass of solution = Volume of solution x Density of solution
Mass of solution = 450 ml x 1.1 g/ml
Mass of solution = 495 g
Step 2: Determine the mass of the solute (hydrogen peroxide) in the solution:
Mass of solute = Mass of solution x Percentage concentration of the solute
Mass of solute = 495 g x 0.35
Mass of solute = 173.25 g
Therefore, the mass of solute (hydrogen peroxide) in a 35% solution, using 450 ml of the solution, is approximately 173.25 grams.
To calculate the mass of solute in a solution, we need to know the concentration of the solution and the volume used. In this case, the concentration is given as 35%, and the volume used is 450 ml.
Step 1: Convert the percentage to a decimal. Divide the given percentage by 100.
35% = 35/100 = 0.35
Step 2: Calculate the mass of the solute using the concentration and volume. Multiply the concentration (in decimal form) by the volume.
Mass of solute = Concentration x Volume
Mass of solute = 0.35 x 450 ml
Step 3: Make sure the volume is in the correct unit for the calculation. In this case, ml should be converted to grams.
To do this, we need to know the density of the solution or the molar mass of the solute. Since we don't have that information, we cannot convert from ml to grams.
Therefore, we cannot calculate the mass of the solute in this solution without additional information.
