Step 1: Calculate the weight of each element in 1 kg of coal.
The total weight of coal is 1 kg.

  • Weight of Carbon (C) = 0.90×1 kg=0.90 kg0.90 \times 1 \text{ kg} = 0.90 \text{ kg}
  • Weight of Hydrogen (H2H_2) = 0.035×1 kg=0.035 kg0.035 \times 1 \text{ kg} = 0.035 \text{ kg}
  • Weight of Oxygen (O2O_2) = 0.030×1 kg=0.030 kg0.030 \times 1 \text{ kg} = 0.030 \text{ kg}
  • Weight of Nitrogen (N2N_2) = $0.010 \times
