A compound contains only carbon, hydrogen, and oxygen. Combustion of 70.86 g of the compound yields 103.9 g of CO₂ and 42.52 g of H₂O. The molar mass of the compound is 120.104 g/mol. *Each part of this problem should be submitted separately to avoid losing your work* 1. Calculate the grams of carbon (C) in 70.86 g of the compound: 2.361 2. Calculate the grams of hydrogen (H) in 70.86 g of the compound. [4.767 3. Calculate the grams of oxygen (O) in 70.86 g of the compound. [63.73 There is 1 mole of C present in CO₂ and 12.01 g of C in 1 mole of C. Starting with 103.9 g of CO2, set up your equation so the units cancel and only grams of C remain. All the carbon that came from the compound ended up as carbon in the 103.9 g of CO₂ produced in the combustion reaction. Remember, there is 44.01 g of CO₂ in 1 mole of CO₂. By sig fig rules, your answer should have four sig figs. There are 2 moles of H present in H₂O and 1.008 g of H in 1 mole of H. Starting with 42.52 g of H₂O, set up your…
