Answer

Explanation:

Step1: Recall density formula

Density $\rho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Calculate density of Metal A

For Metal A, $m = 41.63\ g$ and $V=80.7\ mL$. So $\rho_A=\frac{41.63}{80.7}\ g/mL\approx0.52\ g/mL$.

Step3: Calculate density of Metal B

For Metal B, $m = 40.01\ g$ and $V = 45.40\ mL$. So $\rho_B=\frac{40.01}{45.40}\ g/mL\approx0.88\ g/mL$.

Answer:

  1. Density of Metal A: Approximately $0.52\ g/mL$
  2. Density of Metal B: Approximately $0.88\ g/mL$
