Final answer:
The mass of 3.00 L of pure water is 3.00 kg. The mass of 3.00 L of whole blood is 3.15 kg. The mass of 3.00 L of seawater is 3.09 kg.
Step-by-step explanation:
To calculate the mass of a substance, you need to multiply its density by its volume.
For pure water, the density is 1.00 g/cm³. So, the mass of 3.00 L of pure water would be:
Mass = Density x Volume
Mass = 1.00 g/cm³ x 3000 cm³ = 3000 g = 3.00 kg
Similarly, you can calculate the mass of 3.00 L of whole blood and seawater using their respective densities:
For whole blood, the density is 1.05 g/cm³. So, the mass of 3.00 L of whole blood would be: Mass = 1.05 g/cm³ x 3000 cm³ = 3150 g = 3.15 kg
For seawater, the density is 1.03 g/cm³. So, the mass of 3.00 L of seawater would be: Mass = 1.03 g/cm³ x 3000 cm³ = 3090 g = 3.09 kg
