✔ 最佳答案
(a) AgCl---Silver chlorideformula mass: 107.9+35.5=143.4
(b) ZnO---Zinc oxide
formula mass: 65.4+1=81.4
(c). (NH4)2CO3---Ammonium carbonate
formula mass: (14+4)*2+12+3*16=96
(d). Na2SO3---Sodium sulphite
23*2+32.1+16*3=126.1
(e). Cu(NO3)2---Copper(II) Nitrate
formula mass: 63.5+(14+16*3)*2=187.5
