This problem has been solved! х STARTING AMOUNT *( ) 42.09 1 36.03 6.022 x 1023 |4.15 х 1023 12.01 0.694 25.0 0.594 1.01 g C3H6 molecules C3H6 mol C3H6 g C3H6/mol Since we have 0.27 moles we multiply our weight by 0.27. moles (C 3 H 6) = 0.5941 mol. So is it 18g of carbon and 4g of C3H8 in 0.500 mols of C3H8? Now, calculate the proportion to get moles of C2H6: 25.1 grams / (30.0 grams / mol) = 0.83 mol C2H6. When you are talking about 1 mole of sucrose, it's the same as saying 1 mole of sucrose atoms, so there are Avogadro's number of atoms in one mole of sucrose (or carbon, or anything measured in moles). moles = mass/mrn = 6/12n= 0.5 Need help with . ? An unknown compound contains only carbon, hydrogen, and oxygen (CxHyOz). The answer is 42.07974. one molecule of CH₄ contains 1 atom of carbon and 4 atoms of hydrogen . If you have 12.0 moles of iron, for complete reaction you need: (HINT you need the balanced chemical reaction!) 4.4897 moles of propane has 3*4.4897 =13.47 moles carbon or 13.47 * 6.022*10^23 = 81.11*10^23 atoms of carbon [ Avagadro's constant, 1 mole = 6.02 × 10^23 atoms or molecules, in this case it is atoms ].
