1. Before going through the explanation of the investigators' model, take a few minutes to think about ways that you could produce a histogram for IPI that represents individual
variation at 21.1.C but still includes all the data that were collected. Remember that
there can be more than one right answer, so be creative and try to evaluate the
advantages and disadvantages of a few different approaches.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
