A test is being developed to determine if impurities in the fuel will impact fuel consumption. In a 750 milliliter [ml] sample, 1.7 grams [g] of Impurity A are measured. Impurity A has a molecular mass of 278 grams per mole [g/mol). What is the molarity of Impurity A in units of moles per milliliter [mol/mL) in the sample? The molarity of Impurity A is = ..... [mol/mL).
