Organic Chemistry Question:

Answer #1
Take 100ml water and pore 10gr NaOH
pellets sterr with gently boil. NaOH sol ready

Answer #2
Water density1 so take 90 ml water and 10 g NaoH
Shake.i.e the 100ml soln of NaoH.

Answer #3
90ml water with 10gm naoh pellets stirred in it makes 100ml solution.

Answer #4
10gms of Na pillets dissolved in 100ml of water. 10gms of Na pillets are react with water thermally heat produce. so 1 or 2 pillets added to water and cool by the help of tap water. continiue this process along 10gms of Na pillets dissolving in 100ml of water then 10%NaoH solution prepared.

Answer #5
10gm naoh + 90ml water = 100ml sol.
