An aerospace engineer measures a structural specimen of a new titanium-aluminium alloy. The specimen has a mass of 3.15 kg and a volume of 4.20 × 10-4 m3.
What is the density of the alloy?
Use the equation:
density=massvolume \text{density} = \frac{\text{mass}}{\text{volume}} density=volumemass1.33×10−4 kg/m31.33 \times 10^{-4}\text{ kg/m}^31.33×10−4 kg/m3
