A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density? A. 0.37g/mL B. 2.7g/mL c 9.09g/mL D 11.75g/mL

To find the density of the aluminum block, we can use the formula for density:<br /><br />\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]<br /><br />Given:<br />- Mass of the aluminum block = 40.5 g<br />- Volume of the aluminum block = 15.0 mL<br /><br />Plugging in the values:<br /><br />\[ \text{Density} = \frac{40.5 \, \text{g}}{15.0 \, \text{mL}} \]<br /><br />\[ \text{Density} = 2.7 \, \text{g/mL} \]<br /><br />Therefore, the correct answer is:<br /><br />B. $2.7g/mL$
