A symbol for mol/kg is often used. It is a lower-case m and is often in italics, m. Some textbooks also put in a dash, like this: 1.00-m.However, if you write 1.00 m for the answer, without the italics, then that usually is correct because the context calls for a molality. gps w farming simulator 22 link w opisiehttp://gorechem.weebly.com/uploads/3/7/7/8/37784611/mole_to_mass_to_atoms.pdf gps wilhelmshaven duales studium
