Can you me with this? a student found the rock shown here and weighed it to determine its mass. what steps should the student take to find its density? a-determine it’s volume by how much water it displaces, then divide mass by volume b- determine its volume by multiplying length x width x height, the. divide mass by volume c- crush the rock to a powder and measure its volume in a graduated cylinder, then divide mass by volume d- determine its volume using the formula for the volume of a sphere (v= 4/3•r to the 3 power), then divide mass by volume

The density of a rock will be measured by placing it into a graduated cylinder partially filled with water, and then measuring the volume of water displaced. the density d is given by d = m/(v1 − v0), where m is the mass of the rock, v0 is the initial volume of water, and v1 is the volume of water plus rock. assume the mass of the rock is 750 g, with negligible uncertainty, and that v0 = 500.0 ± 0.1 ml and v1 = 813.2 ± 0.1 ml. estimate the density of the rock, and find the uncertainty in the estimate.

The density of a substance is the ratio of its mass to its volume. the formula for density is: d = mass/volume. if the density and the volume of a liquid are known, its mass can be found by a) adding its density to its volume. b) dividing its density by its volume. c) multiplying its volume and density. d) subtracting its density from its volume
