Question
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 equation so the units cancel and only grams of H remain. Use 18.02 for the molar mass of water and by sig fig rules, your answer should have four sig figs. To find how many grams of oxygen you have, subtract the mass of C and H you calculated above from the total mass of the compound. By sig fig rules, your answer should be rounded to two decimal places. Submit Answer Incorrect. Tries 1/99 Previous Tries Based on your previous answers, calculate 1. the moles of carbon (C) in 70.86 g of the compound: 2. the moles of hydrogen (H) in 70.86 g of the compound: 3. the moles of oxygen (0) in 70.86 g of the compound: grams grams grams Submit Answer Tries 0/99 Enter the correct subscript for each atom using the smallest whole number.
