SUMMARY
The discussion revolves around calculating the number of moles of ions in a 250 mL solution of 4.4 M sodium sulfate (Na2(SO4)). The correct calculation reveals that the solution contains 3.3 moles of ions, derived from the dissociation of sodium sulfate into three ions: two sodium ions (Na+) and one sulfate ion (SO4^2-). Additionally, a related question discusses the production of hydrogen gas (H2) from the electrolysis of water, emphasizing the need to understand the electron transfer involved in the reaction.
