Which of the following is closest to the density of titanium at room temperature?

• A. 4.51 g/cm^3
• B. 2.70 g/cm^3
• C. 19.32 g/cm^3
• D. 7.87 g/cm^3

Answer: (A)

Verified step by step guidance

1. Understand that density is defined as mass per unit volume, given by the formula \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
2. Recognize that the problem asks for the density of titanium at room temperature, which is a known physical property that can be found in reference tables or reliable sources.
3. Recall or look up the standard density value of titanium at room temperature, which is typically around 4.5 g/cm\(^{3}\).
4. Compare the given options (2.70 g/cm\(^{3}\), 19.32 g/cm\(^{3}\), 7.87 g/cm\(^{3}\)) to the known density of titanium to identify which is closest.
5. Select the value closest to the known density of titanium, which is approximately 4.51 g/cm\(^{3}\).
