Answer 1

To find out how many grams of blood are lost when donating 1.00 pint, the volume of a pint (473 mL) is multiplied by the density of blood (1.05 g/mL) yielding a mass of approximately 497 grams. The correct option is (E)

Step-by-step explanation:

If your blood has a density of 1.05 g/mL (at 20 °C), to determine how many grams of blood you would lose if you donated 1.00 pint, you need to use the unit conversion factor. First, we should convert pints to milliliters (mL), as the density is given in grams per milliliter. From the conversion factors provided, we know 1 pint = 473 mL. Therefore, 1 pint of blood is equivalent to 473 mL.

Now, using the formula:

mass (g) = density (g/mL) × volume (mL)

We can calculate the mass of blood donated:

mass (g) = 1.05 g/mL × 473 mL

mass (g) = 496.65 g, which can be rounded to 497 g for practical purposes. Thus, the correct answer is E. 497 g.
