Final answer:
Using the density of blood at 1.06 g/mL and the volume donated at 473.176 mL, the mass of blood Keona donates is 501.57 g to the nearest hundredth of a gram.
Step-by-step explanation:
The mass of the blood Keona donates can be calculated using the density of the blood and the volume she donates. The density of blood is given as 1.06 g/mL, and she donates one pint, which is equal to 473.176 mL. To find the mass, we use the equation that relates density (p), mass (m), and volume (V): p = m/V. To find the mass, we rearrange this to m = p × V.
Substituting the values we have:
m = 1.06 g/mL × 473.176 mL
Calculating this gives a mass of m = 501.56736 g, which rounded to the nearest hundredth of a gram is 501.57 g.
