A hemoglobin (Hgb) test measures 14.5 grams (8) of Hgb per 100 milliliters (mL) of blood. If the patient has 5 5 quarts (g) of blood in her body, how many grams of Hgb are present? (Hint: 1 qt = 1,000 mL)

Answer:

The patient has 797.5 grams of Hemoglobin

100 mL of blood contains = 14.5 grams of Hgb

1 mL of blood contains = 0.145 grams of Hgb

5.5 quarts of blood = 1000×5.5 mL of blood = 5500 mL of blood

Hence, 5500 mL of blood will have = 0.145×5500 grams of Hgb = 797.5 grams of Hgb

Therefore, the patient has 797.5 grams of Hemoglobin.
