a.) dik konsentrasi 0,1M, Volume 200 ml MrNaOH= 23+1+16= 40
M= m/Mr x 1000/v
0,1 M = m/40 x 1000/200
0,1M =5 m/40
0,1M= m/8
10m=8
m=0,8 gr
b.) v x /Mol N = V x /Mol SO3
15 /m/14 =5 / 4/(32 +3 x 16)
210/m=100
m= 2,1 gr
a.
M= gr/Mr x ml/1000
0.1= gr/40 x 200/1000
0.1= gr/40 x 1/5
Gr = 20gr
b.
n1/n2 = v1/v2
nN2/nSO3 = vN2/vSO3
X/0.05 = 15/5
X=4,2gr
Catatan: cara mencari mol SO3 yaitu:
n=gr/Mr
n=4:80 = 0.05
