Answer : The emperical formula of hydrocarbon is .
Solution : Given,
Mass of = 11.1 g
Mass of = 5.11 g
Step 1 : convert given mass in moles.
Moles of = = = 0.2522 moles
Moles of = moles of C = 0.2522 moles
Moles of = = = 0.2838 moles
Moles of = moles of H = 0.2838 × 2 = 0.5677 moles
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C = 0.2522/0.2522 = 1
For H = 0.5677/0.2522 = 2.25
C : H = 1 : 2.25
To make the ratio as a whole number multiply numerator and denominator by 4.
Ratio of C : H = = 4 : 9
The mole ratio of the element is repersented by subscripts in emperical formula.
Therefore, the Emperical formula =
