Dilution and Concentration of Liquids Determination of Percentage or Ratio Strength Concentration calculator allows you to calculate molar concentration, mass of compound, volume and formula weight of a chemical solution. 2020-07-26 · concentration = \(\frac{\textup{mass~of~solute~in~g}}{\textup{volume~in~dm}^3}\) concentration = \(\frac{\textup{8~g}}{\textup{2~dm}^3}\) concentration = 4 g/dm 3 The formula of mass concentration is as follows. Here, ρ i is the mass concentration of the i -th solute, m i is the mass of the i -th solute, and V is the volume of the solution. Note: The notation for mass concentration as well as density is ρ .
