(a) The number of times one atom of an element is heavier than $\dfrac{1}{12}$ th the mass of an atom of carbon [C¹²] is known as the Relative Atomic Mass [RAM] of the element.

RAM = $\dfrac{\text{Mass of one atom of the element }}{\dfrac{1}{12} \text{th the mass of an atom of carbon }}$

(b) Saturated aliphatic hydrocarbons containing carbon-carbon single bond are known as alkanes. They are also known as paraffins and have the general formula as C_nH_2n+2
