Berapa presentase Carbon dan Nitrogen pada pupuk urea denga rumus kimia CO(NH2)2
reinaldijuniarto
JML N C = 1 O = 1 N = 2 H = 4 jd terdiri dr 8 unsur 8/100 = 12,5
jd C = 1. 12,5 = 12,5% N = 2 . 12,5 = 25 %
smg aj btul...hhh

Mr = 1.Ar C + 1. Ar O + 2. Ar N + 4. Ar H = 12 + 16 + 28 + 4 = 60
% C dalam urea = jmlh atom C * Ar C / Mr urea X 100 % = 1*12/60 X 100% = 20 % % N dalam urea = jmlh atom N * Ar N / Mr urea X 100% = 2 * 14/60 X 100% = 46,7 %
C = 1
O = 1
N = 2
H = 4
jd terdiri dr 8 unsur
8/100 = 12,5
jd C = 1. 12,5 = 12,5%
N = 2 . 12,5 = 25 %
