a) Clean and dry the density bottle and weigh it along with the stopper (W1 in g).
b) Select about 25 gm of dry soil free of clods and put the same into the density bottle. Weigh it with brass cap and washer (W2 in g).
c) Fill the density bottle with de-aired water up to half its height and stir the mix with a glass rod. Add more water and stir it. Place the stopper on top and take the weight (W3 in g).
d) Remove all the contents from the density bottle, clean it thoroughly and fill it with distilled water. Weigh it (W4 in g).
e) Use above equation for determining G.
f) Repeat the same process for additional tests.
