<span>AgCl(s) → Ag+(aq) + Cl-(aq) That would be my best guess</span>
V=2.90 L
c=1.8 mol/L
n(NaOH)=vc
n(NaOH)=2.90L*1.8mol/L=5.22 mol
For this question, you must know that there are 6.022e23 atoms/molecules per mole of any substance (this is Avogadro's number). Therefore, your answer is 6.022e23 * 1.60 = 9.64e23 molecules of sulfur dioxide. (the "e" represents "times ten to the power of ___ ")
