# A solution contains non volatile solute of molecular mass $M_2$ . Which of the following can be used to calculate the molecular mass of solute in terms of osmotic pressure : - Note :$m_2$ → mass of solute V → Volume of solution p → Osmotic pressure
( A ) $m_2 =[\frac{m^2}{V}]VRT$
( B ) $m_2 =[\frac{m^2}{V}]\frac{RT}{\pi}$
( C ) $m_2 =[\frac{m^2}{V}]\frac{\pi}{RT}$
( D ) $m_2 =[\frac{m^2}{V}]\pi RT$
