Haemoglobin contains 0.25% iron by weight, the molecular weight of Haemoglobin is 89600, calculate the weight (in g) of ${\mathrm{K}}_4\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]$ that can be produced if all the iron atoms from 4.48 kg haemoglobin are converted into ${\mathrm{K}}_4\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]$ through a series of reaction. Give your answer to the nearest integer.
