Soalan
Berapakah jisim bagi 7.12 mol NaI. [Jisim Atom Relatif: Iodin = 131; Natrium = 23]
Jawapan:
Jisim formula relatif NaI = 23 + 131 = 154.
Jisim 7.12 mol NaI
= Bilangan mol x Jisim formula relatif of NaI
= 7.12 x 154
= 1096.48g
Berapakah jisim bagi 7.12 mol NaI. [Jisim Atom Relatif: Iodin = 131; Natrium = 23]
Jawapan:
Jisim formula relatif NaI = 23 + 131 = 154.
Jisim 7.12 mol NaI
= Bilangan mol x Jisim formula relatif of NaI
= 7.12 x 154
= 1096.48g
