Calculation: - Let the mass of the compound be 100 gm. The chemical formula of it is CO2. Oxygen is necessary in sustaining life and considered as a precious gem since it cannot be found in space. The oxygen:carbon ratio is 1.018, or approximately 1, and the hydrogen:carbon ratio is approximately 2. The formula for carbon dioxide is CO 2, that means one atom of carbon and two atoms of oxygen. â The mass of zinc = 52 gm â The mass of carbon = 9.6 gm â The mass of oxygen = 38.4 gm - No of moles of Zinc = 52/65 = 0.8 - No of moles of Carbon = 9.6/12 = 0.8 - No of moles of oxygen = 38.4/16 = 2.4 â Zn : C : O = 0.8 : 0.8 : 2.4 5 volumes of oxygen. Step 3: Count the number of carbon atoms in the alkanone molecule. The resultant mixture contained 2 volumes of water vapour and 2 volumes of carbon dioxide. Step 4: Write the number of of carbon atoms into the skeleton molecular formula as a subscript number to the right of the symbol for carbon (C). For the reaction of carbon with a plentiful source of oxygen, as we have noted, the sole product is carbon dioxide. A. C2 and O B. C2 and O2 C. C and O2 D. CO2 and O2 Thus, the mole ratio of carbon to oxygen and hydrogen to oxygen is 4 : 1 and 8 : 1. Step 4: We can write the empirical formula by placing the numbers as the subscript to the elementâs symbols. The ratio between carbon and oxygen is 1:2.The elements present in this compound are carbon and oxygen. The empirical formula of the given compound. What is the chemical formula for each of the reactants? We can write an equation for this reaction: The plus sign indicates that carbon and oxygen react, and the arrow, usually read as âyields,â points to the result of their reaction: carbon â¦ Determine the formula of the compound. All volumes were measured in identical conditions. Step 2: Write a skeleton molecular formula using the symbols for carbon (C), hydrogen (H) and oxygen (O). The empirical formula of glucose is therefore CH 2 O, but what is its molecular formula? However, based on the studies, molecular oxygen â¦ Chemistry The Mole Concept Percent Composition 1 Answer The atomic mass of carbon is 12 grams per mole. C H O . The gas oxygen that is in the "air" has the formula O 2. Whatâs the empirical formula of a molecule containing 18.7% lithium, 16.3% carbon, and 65.0% oxygen? Carbon dioxide is made of carbon and oxygen atoms. Therefore, the empirical formula is C 4 H 8 O. Carbon and oxygen bond to form carbon dioxide. One volume of a compound of carbon, hydrogen and oxygen was exploded with 2. If we start with: [math]CO^- + O_2 -> CO_2[/math] The balanced equation will be: [math]2CO^- + O_2 -> 2CO_2[/math] So one mole of O 2 weights : 2 x 16 = 32 grams Oxygen has an atomic mass of 16 gram per mole.
