Express your answer with the appropriate units Hints H0'1 Value Units My Answers Give Up 7 8 9Explanation / Answer
no of moles of HBr = 8*10^-3 moles
volume of solution = 13L
molarity = no of moles/volume in L
= 8*10^-3/13 = 0.000615 M
HBr---------> H^+ (aq) + Br^- (aq)
0.000615M 0.000615M
[H^+] = [HBr]
[H^+] = 0.000615M
{OH^-] = Kw/[H^+]
= 1*10^-14/0.000615
= 1.62*10^-11M
part-B
molarity = W/G.m.Wt* volume of solution in L
= 4/40*3 = 0.033M
NaOH --------> Na^+ (aq) + OH^- (aq)
0.033M 0.033M
[H3O^+] = KW/[OH^-]
= 1*10^-14/0.033 = 3.03*10^-13 M
