Calculate the concentration (M) of sodium ions in a solution made by diluting 30.0 mL of a 0.574 M solution of sodium sulfide to a total volume of 150 mL.
Answer:-
Sodium sulfide = Na2S
So, 1 mole Na2S = 2 mole Na+
So, moles of Na+ in 30.0 mL = 2 x 0.574 x 30.0/1000
= 0.03444 mol
So, [Na+] = 0.03444 x 1000/150
= 0.2296 M
= 0.230 M
