What volume of solution would be needed to deliver the stated amount of solute?
39.0 grams of solute from a solution that is 16.0 % m/v?
(anwser in milliliters
16% m/v means 16 g solute in 100 mL soln.
100 mL x (39.0 g/16 g) = ?
To determine the volume of solution needed, we first need to calculate the mass of the solute in the solution. We can then use the mass percent information to find the mass of the solution. Finally, we can convert the mass of the solution into volume by assuming the density of the solution is 1 g/mL.
Step 1: Calculate the mass of the solute in the solution.
Given: Mass percent = 16.0% m/v, Mass of solute = 39.0 grams
Mass percent = (mass of solute / mass of solution) x 100
Rearranging the formula, we can find the mass of the solution:
Mass of solution = (mass of solute / (mass percent / 100))
Mass of solution = (39.0 g / (16.0 / 100)) = (39.0 g / 0.16) = 243.75 g
Step 2: Convert the mass of the solution into volume.
Density of the solution = 1 g/mL
Volume of solution = Mass of solution / Density of the solution
Volume of solution = 243.75 mL
Therefore, the volume of solution needed to deliver 39.0 grams of solute from a solution that is 16.0% m/v is 243.75 milliliters.
