You work with two amino acids. Tryptophan (MW=204 Da) and Methionine (MW=149 Da). You make varioussolutions of each amino acid separately and compare them When you compare two solutions at the same percentage concentration (e.g. 1%), there are moremoles of Tryptophan in solution than moles of Methionine because the molecular weight of Tryptophan ishigher. When you compare two 1-liter solutions containing these amino acids at a 10mM concentration, thereis the same number of amino acid molecules in each solution
