a) Elemental analysis of an unknown sample shows its mass composition to be 49.45% carbon (C), 28.84% nitrogen (N), 16.46% oxygen (O) and 5.18% hydrogen (H). Using mass spectrometry, you determine that the molar mass of the compound is equal to 194.19 g/mol. What is the molecular formula of the unknown compound? b) We carry out combustion of C5H10O (molar mass = 86.13 g/mol) (its reaction with O2, to produce CO2 and H2O). What is the maximum mass of products obtained (CO2 (molar mass = 44.01 g/mol) and H2O (molar mass = 18.02g/mol)), if the reaction vessel contains 15.0 g of C5H10O and 1.00 mol of Oz.
