Answer: A.) 0.029

Explanation: To calculate the moles, we use the equation:


\text{Number of moles}=\frac{\text{Given mass}}{\textMolar mass}}

For sodium:

Mass of sucrose given = 10 g

Molar mass of sucrose
C_(12)H_(22)O_(11) = 342 g/mol

Putting values in above equation, we get:


\text{Moles of sodium}=(10g)/(342g/mol)=0.029mol

Thus the number of moles of sucrose available for this reaction will be 0.029.
