Material 5296

What material is the casting that weighs 45.2 g and has a volume of 4 cm³? If it is a simple chemical element, write its chemical symbol.

Correct answer:

x = Pb

Step-by-step explanation:

$$\begin{gathered} m=45.2\text{g} \\ V=4{\text{cm}}^3 \\ \rho =\frac{m}{V}=\frac{45.2}{4}=\frac{113}{10}=11\frac{3}{10}=11.3{\text{g/cm}}^3 \\ x=Pb \end{gathered}$$
