Questions & Step-by-Step Solutions

What is the mass percent of a solution containing 10 g of solute in 90 g of solvent?
  • Step 1: Identify the mass of the solute. In this case, the mass of the solute is 10 g.
  • Step 2: Identify the mass of the solvent. In this case, the mass of the solvent is 90 g.
  • Step 3: Calculate the total mass of the solution by adding the mass of the solute and the mass of the solvent. Total mass = 10 g + 90 g = 100 g.
  • Step 4: Use the mass percent formula: Mass percent = (mass of solute / total mass of solution) x 100.
  • Step 5: Substitute the values into the formula: Mass percent = (10 g / 100 g) x 100.
  • Step 6: Calculate the mass percent: (10 g / 100 g) x 100 = 10%.
