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

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
