<reasoning>

Apply the law of conservation of mass

\[
\text{Mass of Reactants} = \text{Mass of Products}
\]

Relate reactants to products

\[
\text{Mass of (Sodium + Hydrogen + Oxygen)} = \text{Mass of Compound}
\]

Determine the correct relationship

\[
\text{Mass of Compound} = \text{Sum of the masses of the individual elements}
\]
