  • Symbols and Meanings (Unit)

  • $AM$ = atomic mass (atomic mass unit (amu))
  • $RAM$ = relative atomic mass
  • $m$ = given mass (gram (g))
  • $n$ = number of moles (mol)
  • $RMM$ = relative molecular mass
  • $MM$ = molar mass (gram/mole (g/mol))
  • $C$ = concentration ($mol/dm^3$) or (mol/L)
  • $V$ = volume ($dm^3$) or Liters (L)
  • $P$ = pressure (atmosphere (atm)) or (mmHg)
  • $T$ = temperature (Kelvin (K))
  • $C_A$ = molar concentration of the acid $(mol/dm^3)$
  • $C_B$ = molar concentration of the base $(mol/dm^3)$
  • $V_A$ = volume of the acid $(dm^3)$
  • $V_B$ = volume of the base $(dm^3)$
  • $n_A$ = number of moles of the acid $(mol)$
  • $n_B$ = number of moles of the base $(mol)$
