1) A2 = 18 (0,2) (0,31)2
(4 – 2,0) (2,0 X 9,81)
= 3,6 (9,61X10-2)
2 X 19,62
= 34,59 X 10-2
39,24
= 0,88 X 10-2
= 8,8 X 10-3 → 8,8 µm
2)
3) Dik : p = 7,203 g/cm3
ɯ = 181,3 g
Vb = 60,0 cm-3
Dit : g = …….?
Peny : p = g/cm3
7,203 = 181,3 / cm3
Cm3 = 25,17
£ = Vb – Vp = l Ve
=
vb
Vb
= 60 – 25,17
60
= 0,58 atau 58 %
4) p = m
v
Dik = p = 3,89 g/ml
v = 25 ml
Ditanyakan = m
Peny
=p=m
v
m=pxv
m = 3,89 g/ml x 25 ml
m = 97,25 g
5) Dik : p = 5,033
£ dalam partikel = 78 %
Dit : pg
Peny : £ dalam partikel = l – pg
p
78 % = l – pg
5,033
pg = l – 78% x 5,033
pg = l – 0,78 x 5,033
pg = l – 3,92
pg = - 2,92
