# A piece of meta ha a density of 11.3 g/cm^3 and a volume of 6.7 cm^3. What is the mass of this piece of metal?

$\text{Mass} \cong 75 \cdot g$
$\rho , \text{ density } =$ $\text{Mass"/"Volume}$.
Thus $\text{Mass}$ $=$ $\rho \times \text{volume}$ $=$ $11.3 \cdot g \cdot \cancel{c {m}^{-} 3} \times 6.7 \cdot \cancel{c {m}^{3}}$
$=$ ??*g*cm^3.
