1. Given,

   Molar Mass:

   Carbon Dioxide = (12+16*2) g

   = 44 g

   Sodium Carbonate = (23+12+48) g

   = 83 g

   Aluminium Nitride = (27+14) g

   = 41 g

   1. Carbon Percentage = (12/44)*100%

   = 27.27%

   2. Sodium Percentage = (23/83)*100%

   = 27.71%

   3. Aluminium Percentage = (27/41)*100%

   = 65.85%

   I hope this helps.
