number of moles of hydrogen =

To get the whole number of mole we divide it by - 0.8714

we get moles of carbon = 1

we get moles of hydrogen = 1.84 = 2

multiplying by factor 2 to get the whole number-

we get empirical formula as =

Molecular formula = to find molecular formula , we determine how many empirical formula it takes to make 1 molecular formula =

molar mass of

molecular fomula will be

B) To balance the combustion equation using molecular formula-
