Answer :

1. 4 moles of nitroglycerine ; CO2 (12) + N2(6) + O2(1) = 19 moles of


gas molecules are formed.


2. 4 moles of nitroglycerine gives 19 moles of gas molecules. So, 1 mole


of nitroglycerine gives (19/4) 4.75 moles of gas molecules.


3. Gram molecular mass of nitroglycerine is 1 mole of nitroglycerine.


So, mass of 1 mole of nitroglycerine is 227 grams.


[(3x12)C + (5x1)H + (3x14)N + (9x16)O]
