Question

Ce cantitate de AgNO3 contine aceeasi cantitate de azot ca 68g de NH3? Am nevoie urgent

Answer 1

M.NH3= 14+3x1 = 17 g/mol

M.AgNO3 = 108+14+3x16 = 170 g/mol

17 g NH3 ............................ 14 g N

68 g NH3 .......................... m = 56 g N

170 g AgNO3 ................... 14 g N

M .......................................... 56 g N

= 680 g AgNO3
