A 0.5347 g sample of cinnamaldehyde, a compound that contains only carbon, hydrogen and oxygen and has the fragrance of cinnamon was combusted in a flow of excess oxygen. The carbon dioxide collected had a mass of 1.6024 g and the water collected had a mass of 0.2916 g. When cinnamaldehyde was vaporized in a 254.00 mL flask at 100.0 °C and 1.044 bar, the vapour was found to have a mass of 1.1302 g. Given that the unknown compound contained 0.4373 g carbon and 0.03269 grams of hydrogen, what mass of oxygen (O), in grams, were present in the cinnamaldehyde sample?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete - the lime absorbs CO₂ from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 550. L and heated to 520.0 °C. When the amount of CaCO3 has stopped changing, it is found that 8.46 kg have disappeared. Calculate the pressure equilibrium constant K, this experiment suggests for the equilibrium between CaCO3 and CaO at 520.0 °C. Round your answer to 2 significant digits.
