Explanation / Answer

1).

emperical formula = C4H9

emperical formula mass = 57

molar mass = 114.21 gram/mole

n= molar mass/emperical formula

n= 114.21/57 = 2.0

Molecular formula of the compound = n x emperical formula

                                               = 2 x C4H9 = C8H18.

Molecular formula = C8H18

2)

emperical formual = CCl

emperical formula mass = 45.5

molar mass = 284.77

n= 284.77/45.5= 5.99 = 6.0

molecular formula = 6.0 x CCl

molecular formula = C6Cl6
