Haemoglobin C_(2952)H_(4664)N_(812)O_(832)S_(8)Fe_(4) , molar mass = 65248 g/mol is the oxygen carrier in blood. An average adult has about 5.0L of blood. Every milliliter of blood has approximately 6.0 xx 10^(9) erythrocytes, or red blood cells and every red blood cell has about 3 xx 10^(8) haemoglobin molecules. The mass of haemoglobin molecules in an average adult is : (N_(A) = 6 xx 10^(23))
