What will be the dry density for a sample with the following properties, lying on the zero-air void line on the compaction curve plot? Assume, G=2.67, w

Pampanga sand with G, = 2.51 is mixed 26% by weight of water and compacted to produce a cylindrical %3D sample of 48 mm diameter and 96 mm long with 7% air porosity. Calculate the mass that will be required and the void ratio of the sample.
