A soil report has to be made for a soil deposit. The GSD $($Grainsize distribution$)$ and Hydrometer Analysis for the soil deposit are performed in the lab. Total weight taken for analysis is $500$ gm$.$ The weight of material in each sieve and their corresponding no$.$ are listed below.

$($a$)2$mm $-50\mathrm{.}56$gm

$($b$)1$mm $-65\mathrm{.}45$gm

$($c$)600$ microns $-0\mathrm{.}34$gm

$($d$)425$ microns $-0\mathrm{.}23$gm

$($e$)212$ microns $-48\mathrm{.}73$gm

$($f$)150$ microns $-170\mathrm{.}99$gm

$($g$)75$ microns $-130\mathrm{.}45$gm

i$.$ What is the percentage of Gravels in the soil?

ii$.$ ii$.$V What is the percentage of sand in the soil?

iii. The effective size of the soil grains is

iv$.$ The Coefficient of uniformity for the soil is

v$.$ The Coefficient of curvature for the soil is

vi$.$Classify the soil based on IS classification system.
