If your blood has an average density of 1.05 g/mL at 20oC, how many pounds of blood do you lose when you donate 1.0 pint of blood?

To calculate how many pounds of blood you lose when donating 1.0 pint of blood, we can follow these steps:

1. **Convert the volume of blood from pints to milliliters (mL):**
   \[
   1.0 \text{ pint} = 473.176 \text{ mL}
   \]
   
2. **Use the given density of blood** to convert milliliters to grams:
   \[
   \text{Density of blood} = 1.05 \, \text{g/mL}
   \]
   Multiply the volume by the density to get the mass of the blood in grams:
   \[
   473.176 \, \text{mL} \times 1.05 \, \text{g/mL} = 496.8348 \, \text{g}
   \]

3. **Convert grams to pounds** using the conversion factor \(1 \, \text{pound} = 453.592 \, \text{g}\):
   \[
   496.8348 \, \text{g} \times \frac{1 \, \text{pound}}{453.592 \, \text{g}} = 1.095 \, \text{pounds}
   \]

So, you lose approximately **1.095 pounds** of blood when you donate 1.0 pint.
