Answer:
I think option (D)is not true
Density is given by mass divided by the volume of a substance.
In this case the mass is 0.794 g and the volume is 0.82 cm ×1.45 cm ×1.25 cm = 1.48625 cm³.
Therefore, density = 0.794/ 1.48625
= 0.5342 g/cm³
Thus, the density of lithium metal is 0.5342 g/cm³
A clastic sedimentary rock is
composed of silicate minerals and rock fragments. They are transported by
moving fluids such as sedimentation due to gravity and are deposited in the
area where it stays. They are composed mostly of feldspar, quartz, rock
(lithic) fragments, clay minerals and mica.
