How do we calculate the mass of a substance present in a solution of known concentration and volume. (With formulas )

- Rearrange the concentration equation to: number of moles (mol) = concentration (mol dm^-3 ) x volume (dm^3) -Multiply the moles of solute by its molar mass mass of solute (g) = number of moles (mol) x molar mass(g mol^-1 )
