This compound is an ionic compound...You have the positively charged Na bonding with the negatively charged SO4.  You need to calculate the mass of the sodium in this compound.

There are 5.27 times 2 moles of Na (the positive ion) in this amount of sodium sulphate. If you multiply the number of moles by the atomic weight for sodium (23) you will know how many grams there are in the 5.27 moles of compound.
