Question

A chemistry student decides to rain sample materials from least to most dense she uses a graduated cylinder to measure the volume of the sample through water displacement and she uses an electronic scale to measure the mass of each sample use the data table below the samples from the lowest to highest density

Answer 1

We must know that the volume of sample is the difference between the final and the starter water volume. Furthermore, the density is obtained dividing the mass by the volume of sample. Then, the final table is:

`\begin{center} \begin{tabular}cSample&Mass (g)&\begin{matrix}\text{Starter}\\\text{Water}\\\text{Volume}\\\text{(mL)} \end{matrix}&\begin{matrix}\text{Final}\\\text{Water}\\\text{Volume}\\\text{(mL)}\end{matrix}&\begin{matrix}\text{Volume of}\\\text{Sample}\\\text{(mL)}\end{matrix}&Density\\ A&29.48&10.2&30.9&20.7&1.42\\B&35.43&27.5&37.4&9.9&3.58\\ C&77.58&30.0&44.6&14.6&5.31\\ D&60.06&17.4&29.4&12.0&5.01\\ E&94.25&17.1&20.0&2.9&32.5\\\end{tabular}\end{center}`

The densities were obtained in g/mL. Hence, ranking them:

A < B < D < C < E
