A scientist extrаcted {g} g оf Fe/kg оf sоil using the citrаte-dithionаte bicarbonate (CBD) method. If all crystalline Fe was present as goethite, what is the concentration of goethite, FeOOH, in g/kg soil (i.e. grams of goethite per kg of soil)? The molar mass of goethite is 88.8 g/mol, and the molar mass of Fe is 55.8 g/mol. Round to the nearest 3 significant figures (or at least 2 decimal places).
