A rock weighing 32.0 g is placed in a graduated cylinder displacing the volume from 12.3 mL to 16.8 mL What is density of the rock in g/mL density=[?]g/mL

To find the density of the rock, we need to use the formula:<br /><br />\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]<br /><br />First, calculate the volume displaced by the rock:<br /><br />\[ \text{Volume} = 16.8 \, \text{mL} - 12.3 \, \text{mL} = 4.5 \, \text{mL} \]<br /><br />Next, use the mass of the rock and the volume displaced to find the density:<br /><br />\[ \text{Density} = \frac{32.0 \, \text{g}}{4.5 \, \text{mL}} \approx 7.11 \, \text{g/mL} \]<br /><br />So, the density of the rock is approximately \( 7.11 \, \text{g/mL} \).
