20 g of 20% means you have 20*0.2 - 4 g CaCO3 to start.
pls mark me as brainliest
Answer:
Wet unit weight = 1.94 g/cc
Dry unit weight =1.05 g/cc
density of saturation = 0.41
porosity = 0.43
Explanation:
given data
Void ratio = 0.78
Water content -12%
Specific gravity of solids - 2.68
to find out
Wet unit weight and Dry unit weight and Degree of saturation and Porosity
solution
we know that Wet unit weight formula is
Wet unit weight =
density of water
here Gs is specific gravity of soild and e is void ratio and density of water is 1
so Wet unit weight =
Wet unit weight = 1.94 g/cc
and
Dry unit weight =
density of water
Dry unit weight =
Dry unit weight =1.05 g/cc
and
density of saturation is
density of saturation = Wc × 
her Wc is water content
so density of saturation = 0.12 × 
density of saturation = 0.41
and
porosity is
porosity =
porosity =
porosity = 0.43
