Question

Based on the first and third sketches (Figure 3). what is the density of the block? Assume that the block is 40.0% submerged. Express your answer with the appropriate units. Value Units Submit My Answers Give Up Alternate data Laboratory measurements always contain some error Depending on type of equipment used, that error can be quite substantial. One way the do a completely different experiment to measure of the density of to validate our density value from Part B is to the block, then compare the two measurements. Part C Based on the first and fourth sketches (Eigure 4), what is the density of the block? Express your answer with the appropriate units.

Explanation / Answer

Mass of the block in air, m = 50.0 g.

Suppose V is the volume of the block.

Now, this block floats after 40 % submerging in bromoform.

So, mass of displaced bromoform = 0.40*V*2.890

So, 0.40*V*2.890 = m

=> m/V = 0.40*2.89 = 1.156 g/cm^3

So, the density of the block = 1.156 g/cm^3.
