Answer:
x=2.8moles
Explanation:
first step balance the chemical equation
C2H6+O2-->CO2+2H2O
use more ratio to find the moles of water
1mole of C2H6= 2 moles of H2O
1.4mole of C2H6=?x
cross multiply
x=2.8 moles of H2O

Divide mass by the volume to find density.
First solve the moles of oxgen present in the compound
mol O = 6.93 g O ( 1 mol O / 16 g O )
mol O = 0.43 mol H
then solve the moles of hydrogen present
mol H = ( 7.36 - 6.93) g H ( 1 mol H / 1 g H)
mol H = 0.43 mol H
so the O and H are in the same mole content so the molecular formula would be OH, but the molar mass will not satisfy. so the answer would be
H2O2
