Strategy:
 Normality in a neutralization reaction for a salt like sodium carbonate (which reacts with 2 ) depends on the -factor (). Use the concentration and mass of the hydrated salt to determine the molar mass and then find the degree of hydration ().

Step 1: Calculate equivalents and moles
Normality . Volume .
Equivalents .
Since -factor , Moles .

Step 2: Find molar mass of hydrated salt

Step 3: Solve for x
