Mass Percent Calculator

Compute the mass percent (w/w%) of a solute in a solution from solute and solution masses.

Input Data

Solute
Solution

Results

10
Mass percent = (10 / 100) × 100% = 10%.

At a glance:Mass percent (w/w%) = (solute mass ÷ solution mass) × 100%. Complementary to molarity and dilution calculators.

Formula

w/w% = (m_solute / m_solution) × 100%.

How to Use

  1. Enter the solute and solution masses.
  2. The tool gives the percentage.

Case Studies

10g/100g → 10%

10/100×100 = 10%.

FAQ
