7,18
Diketahui :
masa Oksida timbal (PbxOy) = 7,18 gram
masa Timbal (Pb) = 6,22 gram
masa Oksigen (O) = (7,18 - 6,22) gram = 0,96 gram
Ar Pb = 207 , O = 16
Ditanya : Rumus Molekul PbxOy ?
Jawab :
*Mencari rumus molekul :
Menggunakan Perbandingan mol :
= n Pb : n O
= (gr/Ar) : (gr/Ar)
= (6,22 / 207) : (0,96 / 16)
= 0,03 : 0,06
= 1 : 2
= (x : y = 1 : 2)
Jadi rumus molekulnya adalah :
= PbxOy
= PbO2
