(c) What is the mass, in grams, of 5.20 x 1023 molecules of aspirin, CgH3O4?
(d) What is the molar mass of a particular compound if 0.100 mol weighs 6.64 g?
g/mol
A compound is composed of carbon, hydrogen, nitrogen and oxygen. When a 1.500-g sample of the compound is completely combusted, it yields 1.476 g of CO2and 0.605 g of H2O. In a separate analysis to determine nitrogen, 1.500 g of the compound is found to produce 0.313 g of N2. (a) Calculate the mass percent of each element in the compound. (b) Determine the empirical formula of the compound. (c) If the compound has a molar mass of 134 g/mol, what is the molecular formula?
