Help With Soil Questions...
Any help will be appreciated.
The moist weight of a soil is 16.5 kN/m^3. Given w = 15% and Gs = 2.67
determine;
(a) dry unit weight
(b) porosity
(c) degree of saturation
(d) mass of water, in kg/m3, to be added to reach full saturation
Answers are;
[14.35 kN/m3, 0.452, 48.5%, 233 kg/m3]
Note that γ = gamma
a) dry unit weight
Gs = 2.67
γw = unit weight of water = 9.81
e = 0.826
yd = (Gs * γw * 1) / (1 + e)
γd = (2.67*9.81*1) / 1 + 0.826
= 14.35 kN/m^3
b) Porosityn = e / 1+ e
n = 0.826 / 1 + 0.826
n = 0.452
c) degree of saturation?
d) mass of water, in kg/m3, to be added to reach full saturation
?
Help will be appreciated, thanks.

The Attempt at a Solution
Here is my attempt at solutions, I'm having trouble with the last 2 questions.a) dry unit weight
Gs = 2.67
γw = unit weight of water = 9.81
e = 0.826
yd = (Gs * γw * 1) / (1 + e)
γd = (2.67*9.81*1) / 1 + 0.826
= 14.35 kN/m^3
b) Porosityn = e / 1+ e
n = 0.826 / 1 + 0.826
n = 0.452
c) degree of saturation?
d) mass of water, in kg/m3, to be added to reach full saturation
?
Help will be appreciated, thanks.
