What state of matter takes the shape and volume of its container, like the steam coming from a pot a) gas b) liquid eliminate c) plasma d) solid

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,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
