Question

29. The mass % of NaOH in 5 molal aqueous NaOH
solution is
​

Answer 1

Answer:

16.66%

• Explanation Let mole of solvent be 1 kg Molality =mole of solute /Mass of solvent
• By this formula we get mole of NAOH =5
• MASS OF NAOH =5×40=200
• Total mass of solution = massof solute + mass of solvent =1000+200=1200g

%mass=200×100/1200=16.66%
