Solution;
(a)
Step 1. compute weights of compacted soils: (Weight of compacted soil and mold, kg) – (Weight of empty mold, 2.38kg)
= Weight of compacted soil
Sample 1: 4.09kg – 2.38kg = 1.71kg
Sample 2: 4.11kg – 2.38kg = 1.73kg
Sample 3: 4.06kg – 2.38kg = 1.68kg
Sample 4: 4.14kg – 2.38kg = 1.76kg
Sample 5: 4.11kg – 2.38kg = 1.73kg
Sample 6: 4.14kg – 2.38kg = 1.76kg
Step 2. compute water contents:
(Mass of can and moist soil, g) - (Mass of can and dry soil, g) = Mass of water, W
w
(Mass of can and dry soil, g) – (Mass of can, g) = Mass of solids (soil particle), W
s
w
c
= (W
w ÷ W
s
) × 100 (%) weight of water (g)
weight of solids (g)
w
c
= W
w ÷ W
s × 100 (%)
Sample 1
252.1 - 211.9 = 40.2
211.9 - 21.52 = 190.38
(40.2÷190.38)×100 = 21
Sample 2
239.8 - 202.8 = 37.0
202.8 - 20.28 = 182.52
(37.0÷182.52)×100 = 20
Sample 3
245.5 - 221.6 = 23.9
221.6 - 22.13 = 199.47
(23.9÷199.47)×100 = 12
Sample 4
297.7 - 255.1 = 42.6
255.1 - 23.36 = 231.74
(42.6÷231.74)×100 = 18
Sample 5
223.8 - 199.4 =24.4
199.4 - 25.26 = 174.14
(24.4÷174.14)×100 = 14
Sample 6
277.8 - 242.3 = 35.5
242.3 - 19.74 = 222.56
(35.5÷222.56)×100 = 16
Step 3. compute total unit weight:
(Weight of compacted soil) ÷ (Volume of empty mold, 1000 cm
3
)
Sample 1: 1.71kg ÷ 1000 cm
3
= 0.00171 kg/cm
3
Sample 2: 1.73kg ÷ 1000 cm
3
= 0.00173 kg/cm
3
Sample 3: 1.68kg ÷ 1000 cm
3
= 0.00168 kg/cm
3
Sample 4: 1.76kg ÷ 1000 cm
3
= 0.00176 kg/cm
3
Sample 5: 1.73kg ÷ 1000 cm
3
= 0.00173 kg/cm
3
Sample 6: 1.76kg ÷ 1000 cm
3
= 0.00176 kg/cm

Step 4. compute dry unit weight:
