The in-place density is determined for a soil at a proposed construction site to plan the foundation design. The in-place density test is performed using rubber-balloon equipment with the following results:

• Mass of soil sample obtained from test hole = 1.45 kg

• Volume of test hole = 0.0008 m³

(a) What is the in-place density for the soil?

(b) For the foundation design, it is necessary to use the property of in-place unit weight; convert the in-place density value to unit weight in kN/m³.
