Q6. Ratio of no. of atoms in the molecule

9/12 : 1/1 : 3.5/14 = 0.75 : 1 : 0.25 = 3 : 4 :1

Empirical formula = C₃H₄N;

M.F. = (C₃H₄N)_n

n × Empirical formula mass = Molecular mass

n (3×12+4+14) =108

n × 54= 108

n = 2

M.F. = C₆H₈N₂

 

Q7. g_eq of HCI = 3/36.5 × 2.5 = 0.20548 = g_eq of Al(OH)₃

Weight of AI(OH)₃ = 0.20548 × 78/3

No of tablets = 5342/400 = 13.35 = 14

 

Q8.  BaCO₃ → BaO + CO₂

192 g of BaCO₃ 1 gives mole of CO₂ = 22.4 L

9.85 g of BaCO₃ will give 0.05 mole of CO₂ which is equal to 1.12 litre.
