Mr (C5H7N)x = 162 (5x12 + 7x1 + 14)x = 162 (60 + 7 +14)x = 162 81 x = 162 x = 2 Jadi (C5H7N)2 =

RE : ( C5H7N ) n RM : ( C5H7N)n = Mr (5 x Ar C + 7 x Ar H + 1 x Ar N )n =162 (5 x 12 + 7 x 1 + 1 x 14 ) n = 162 81 n = 162 n = 2 Maka rumus molekulnya = ( C5H7N)2 = C10H14N2 , jadi jawabanya no,5
(C5H7N)x
Mr (C5H7N)x = 162
(5x12 + 7x1 + 14)x = 162
(60 + 7 +14)x = 162
81 x = 162
x = 2
Jadi
(C5H7N)2 =
RM : ( C5H7N)n = Mr
(5 x Ar C + 7 x Ar H + 1 x Ar N )n =162
(5 x 12 + 7 x 1 + 1 x 14 ) n = 162
81 n = 162
n = 2
Maka rumus molekulnya = ( C5H7N)2 = C10H14N2 , jadi jawabanya no,5
