answer: the rock sample is a sedimentary rock.
explanation:
it is given that:
mass of rock sample, m = 2.7 g
volume of rock sample,![v = 1.1 cm^{3}](/tex.php?f=v = 1.1 cm^{3})
so, density of rock sample will be
![density = \frac{mass}{volume}](/tex.php?f=density = \frac{mass}{volume})
![\rho =\frac{2.7}{1.1}g/cm^{3}\\\\\rho =2.45 g/cm^{3}](/tex.php?f=\rho =\frac{2.7}{1.1}g/cm^{3}\\\\\rho =2.45 g/cm^{3})
since, the density of rock sample is
. hence, the rock sample is a sedimentary rock, whose densities varies between
.
