Problem- 50 ml if .15M NaNO was added to a sample containing gallium. Nitrate oxidized Ga(s) to Ga(aq). The resulting nitrous acid was titrated to the equivalence point with 27.82 mL of .1M NaOH. Determine the mass of Ga(s) in the sample

NO3 +3H+ + 2e- ï--> HNO2 + H2O

Ga3+ +3e- ï--> Ga(s)

HNO2ï--> H+ +NO2-

Give me complete explanations of above question thus I can get high score
