Final answer:
Blood has a higher density than water due to its composition which includes proteins, salts, and cells, with a density of approximately 1.060 g/mL compared to water's 1.000 g/mL.
Step-by-step explanation:
No, blood does not have the same density as water. While blood is composed of about 92 percent water, it contains additional substances such as proteins, salts, and cells that increase its density. Specifically, the density of whole blood is approximately 1.060 g/mL, making it slightly denser than water, which has a density of about 1.000 g/mL at room temperature.
Blood's properties such as being more viscous and slightly more acidic than water also contribute to the difference in density. Furthermore, substances when dissolved in water, as seen with blood or urine, generally alter the solution's density compared to pure water.
