Solution

The correct option is C $0.048 g m$ hydrazine, $N_{2} H_{4}$
Molecular formula of glucose- C₆H₁₂O₆

Which means one molecule of glucose contains 12 atoms of Hydrogen.

1 mole of glucose weights 180 g which contains 6.023 × 10²³ molecules of glucose.

So,0.9 g of glucose contains 6.023×10²³ molecules of glucose which means it contains

(6.023×10²³) × 12 X 0.9 atoms of Hydrogen.
