Answer:
So first understand that empirical formula refers to ratio of different atoms in lowest integer form.
To calculate this let's make mol C as our default ratio of 1* and divide everything by 0.528 mol.
Na 1.06/0.528 = 2.00757575758
C 0.528/0.528 = 1
O 1.59/0.528= 3.01136364
Na2CO3
It's sodium carbonate
