Answer:
296.448 g
Explanation:
Density:
we know that density of an object can be measured by dividing its mass to its volume.
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m= mass
V= volume
Given data:
volume= 1.2 cm x 4.00 cm x 3.20 cm =15.36 cm3
density= 19.3 g/cm3
mass=?
Now we will put the values in the formula,
d=m/v
d x V= m
m = 15.36 cm3 x 19.3 g/cm3
m=296.448 g
so the mass of block of gold is 296.448 g
Geologist invented the geologic time scale to keep track of older rocks that have been layered over by newer rocks due to sedimentation that comes from other areas.
Hope this helps
