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
