Question

1. the table below identifies four density groups. according to this classification system, a sample of quartz with a mass of 27 grams and a volume of 10 cubic centimeters should be placed in group a) a b) b c) c d) d

Explanation:

Step1: Calculate the density

Density formula: $
ho=\frac{m}{V}$. Given $m = 27\space g$ and $V=10\space cm^{3}$.
$
ho=\frac{27\space g}{10\space cm^{3}} = 2.7\space g/cm^{3}$

Step2: Determine the group

Since $1.0<2.7<3.9$, the sample should be placed in group $A$.

Answer:

A. Group A
