Question

a chemist has a block of aluminum metal (density is 2.7 g/ml). they drop the metal into a graduated cylinder containing water and find the volume change is 2.3 ml. what is the mass of the block, in g?

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume. We can re - arrange it to $m =
ho\times V$.

Step2: Identify given values

$
ho = 2.7$ g/mL and $V=2.3$ mL.

Step3: Calculate mass

$m=
ho\times V=2.7\times2.3 = 6.21$ g

Answer:

6.21
