The average volume of a red blood cell is 87 μ m 3. The mean concentration of hemoglobin in red blood cells is 0.34 g ⋅ ml - 1. What is the weight of the hemoglobin contained in an average red blood cell?

2.956 * 10 ⁻¹¹ g

Explanation:

The mean concentration of hemoglobin in red blood cell = 0.34 g/ml

average volume of a red blood cell = 87μ m³ where 1 μ m³ = 1 * 10 ⁻¹² ml

average volume = 87 * 1 * 10 ⁻¹² ml = 87 * 10 ⁻¹² ml

weight of hemoglobin contained in an average red blood cell = 87 * 10 ⁻¹² ml * 0.34 g/ml = 2.956 * 10 ⁻¹¹ g
