Answer 1

15) Crven data, Molasitij of Maol = 0.250mg voleme of th504,41=:30 mg Volume Of Naoit zo 112 219.9mL We know that Hy s04 + 2NaOH > Nog 804 + 2H20 Here, 2moles of NaOH reacts with i llisoy So, 1, 3, N2=2. Now, let's consideri Mil - M212 na 0.25 M1 X 30 - Me X 1919. 2 30 Mi = 2,587 My = 2.587 30 -0.0862 m ♡ 0.0829 m option ces correct.
