2Na+ and So4 2-
Full formal set up. 2.88 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(6.022 X 1023/1 mole Na2SO4)(1 mole Na2SO4 atoms/6.022 X 1023) = 0.020 moles of sodium sulfate atoms ------------------------------------------------------( you can see the last two steps are superfluous )
There are many kinds of compounds, and not all of them have both metal and nonmetal types of atoms in them. Carbon dioxide, for example, is composed of two types of nonmetal atoms.
The formula for sodium sulfate is Na2SO4. Therefore, there are 2 sodium atoms, one sulfur atom, and 4 oxygen atoms, for a total of 7.
41,1 g of sodium sulfate (Na2SO4, anhydrous) contain 10,455.10e23 atoms.
