A solution contains non volatile solute of molecular mass M₂. Which of the following can be used to calculate the molecular mass of solute in terms of osmotic pressure?

$${M_2} = \left( {{{{m_2}} \over \pi }} \right)VRT$$

$${M_2} = \left( {{{{m_2}} \over V}} \right){{RT} \over \pi }$$

$${M_2} = \left( {{{{m_2}} \over V}} \right)\pi RT$$

$${M_2} = \left( {{{{m_2}} \over V}} \right){\pi \over {RT}}$$

In electrolysis of NaCl when Pt electrode is taken then H₂ is liberated at cathode while with Hg cathode it forms sodium amalgam

Hg is more inert than Pt

More voltage is required to reduce H⁺ at Hg than at Pt

Na is dissolved in Hg while it does not dissolve in Pt

Conc. of H⁺ ions is larger when Pt electrode is taken.
