Anewly discovered metalloprotein, which contains four atoms of fe per molecule of protein, is found to be 0.600% fe by mass. calculate the molar mass of the metalloprotein.

Let the basis for the calculation of the molar mass of the mellaprotein be 1 mole. If x is the mass of 1 mole of the substance then, 

Each of the mole of iron has a mass of 55.845 g/mol.

         (4 mols of Fe)(55.845 g/ mol) = 223.38 grams

This mass is 0.60% of the total mass of the mellaprotein.

             x = (223.38 grams) / (0.60/100) = 37230 g

37230 grams

B. a graduated substance

Aseasonal prevailing wind in the region of south and southeast asia, blowing from the southwest between may and september and bringing rain (the wet monsoon ), or from the northeast between october and april (the dry monsoon ).
