Results of a standard compaction test (mold volume 943.9 cm3 ) are:

Trial No. 1 Mass of soil + mold 5619g
Mass of mold 3735g
Water content test
Mass of sample + container 288.26g
Mass of dry sample + container 265.39g
Mass of container 104.31g

Trial No. 2 Dry density 1795 kg/m^3 w=14.9%
Trial No. 3 Dry density 1828 kg/m^3 w=15.6%
Trial No. 4 Dry density 1832 kg/m^3 w=16.5%
Trial No. 5 Dry density 1796 kg/m^3 w=17.6%

a. Complete the calculations for trial No. 1.
b. Draw the moisture-density curve using Excel or other spreadsheet programs. Include ZAV curves at w=16%, 17%, and 18%. (The relative density of the soil is 2.65.) Find the maximum dry density and the optimum water content.
