The molecular weight of myoglobin can be calculated as: $ \text{Molecular weight} = \frac{\text{Mass of Fe} \times 100}{\% \text{ of Fe}} = \frac{55.9 \times 100}{0.34} = 16441.18 \text{ g/mol}. $

Group I	Group II
P) NaCl	1) Coordination bond
Q) $H_2$	2) Polar covalent bond
R) $Pd-P$ bond in $Pd(PPh_3)_4	3) Covalent bond
S) $C-Cl$ bond in $CH_3Cl $	4) Ionic bond
