Greg has a blood volume of 5.9 qt. If the density of blood is 1.06 g/mL, what is the mass, in grams, of Greg's blood? (Note: 1 qt = 946.353 mL)

• A. 6,000 grams
• B. 5,930 grams
• C. 5,920 grams
• D. 5,930.5 grams

Answer: (D)

Verified step by step guidance

1. Convert the blood volume from quarts to milliliters using the conversion factor: 1 qt = 946.353 mL. Multiply Greg's blood volume in quarts by this conversion factor to find the volume in milliliters.
2. Use the formula for density, which is \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \), to rearrange and solve for mass: \( \text{Mass} = \text{Density} \times \text{Volume} \).
3. Substitute the known values into the equation: the density of blood (1.06 g/mL) and the volume of blood in milliliters (calculated in the previous step).
4. Perform the multiplication to find the mass of Greg's blood in grams.
5. Ensure the units are consistent throughout the calculation to verify the result is in grams.
