Answer to Question #282521 in Chemistry for dlo

Question

0.1216 gram added to 20 liter of Hcl the acces acid was neutrlized by addition of 50 ml of 0.20 Molar of NAOH find the atomic mass

Answer 1

HCl + NaOH = NaCl + H₂O

According to equation, n (HCl) = n (NaOH).

C_M = n / V

n = C_M x V

n (NaOH) = 0.20 x 0.050 = 0.01 M

n (HCl) = n (NaOH) = 0.01 M
