A solution contains 3.10 g of solute in 10.4 g of solvent. What is the mass percent of the solute in the solution?
% w/w (by mass) = (mass solute/mass solution)*100 = ?
mass solute = 3.10g
mass solution = 3.10g + 10.4g = ?
To find the mass percent of the solute in the solution, we need to divide the mass of the solute by the mass of the solution and then multiply by 100.
Mass percent = (mass of solute / mass of solution) x 100
Given:
Mass of solute = 3.10 g
Mass of solvent = 10.4 g
First, find the mass of the solution:
Mass of solution = Mass of solute + Mass of solvent
Mass of solution = 3.10 g + 10.4 g
Mass of solution = 13.50 g
Now, calculate the mass percent:
Mass percent = (3.10 g / 13.50 g) x 100
Mass percent = 0.2296 x 100
Mass percent ≈ 22.96%
Therefore, the mass percent of the solute in the solution is approximately 22.96%.
To find the mass percent of the solute in the solution, we need to first add up the masses of the solute and solvent to determine the total mass of the solution.
Total mass of the solution = Mass of solute + Mass of solvent
Total mass of the solution = 3.10 g + 10.4 g
Total mass of the solution = 13.50 g
Next, we can calculate the mass percent of the solute by dividing the mass of the solute by the total mass of the solution and multiplying by 100.
Mass percent of solute = (Mass of solute / Total mass of the solution) x 100
Mass percent of solute = (3.10 g / 13.50 g) x 100
Mass percent of solute = 22.96%
Therefore, the mass percent of the solute in the solution is approximately 22.96%.
