Answer is: the molecular formula is C₆H₁₀.
Chemical reaction: C₆Hₓ + yO₂ → 6CO₂ + x/2H₂O.
m(H₂O) = 0.9102; mass of the water.
n(H₂O) = m(H₂O) ÷ m(H₂O)
n(H₂O) = 0,9102 g ÷ 18 g/mol
n(H₂O) = 0,0505 mol.
From chemical reaction: n(H) = 2 · n(H₂O).
n(H) = 0.101 mol.
m(CO₂) = 2.668 g; mass of carbon dioxide.
n(CO₂) = 2.668 g ÷ 44 g/mol.
n(CO₂) = 0.0606 mol; amount of the substance.
n(CO₂) = n(C) = 0.0606 mol.
n(C) : n(H) = 0.606 mol : 0.101 mol.
n(C) : n(H) = 6 : 10; proportion of carbon and hydrogen atoms in cyclohexene.
By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom
