There is no Atomic Number for butane. However, there is a ' Relative Molecular Mass (Mr / MRR). To calculate the Mr (Butane) , you need a copy of the Periodic Table showing the Atomic Masses. Butane has the structural formula ' CH3CH2CH2CH3 ' Reduced to ' C4H10 '. From the atomic masses on the periodic table. we have Carbon(C) @ 12 . there being 4 carbons , so the total mass of the carbon moiety is 12 x 4 = 48 Similarly Hydrogen(H) @ 1 . there being 10 hydrogens , so the total mass of the hydrogen moiety is 1 x 10 = 10 Hence the overall molecular mass (Mr) is 48 + 10 = 58 !!!!! The answer!!!!!
The molar mass of butane is 58,124; for mr explain this abbreviation.

The atoms of Carbon and Hydrogen that form butane, have isotopes. Carbon has isotopic masses of 12 , 13 & 14 Hydrogen has isotopic masses of 1,2 & 3. Theoretically the atomic mass using the heaviest isotopes is 4 x 14 + 10 x 3 = 86 However, this would be very rare, because Tritium ( H -3) is very rare and radio-active. The most common isotopic mass of butane is 4 x 12 + 10 x 1 = 58 NB Do not confuse isotopes with molecular mass. Isotopes of an element are atoms of that element with a different number of neutrons, thereby giving atoms of that element a different mass.
Atomic mass
4 Carbon atoms in one molecule of Butane, times 2 because of two molecules, time the weight of one Carbon atom, which is 12 amu's (an amu = atomic mass unit, also known as a Dalton) equals 96 amu's.
The molar mass of butane (C4H10) is 58.12 g/mol. The molar mass of hydrogen in butane is 10.81 g/mol. To calculate the mass percent of hydrogen in butane, you would divide the molar mass of hydrogen by the molar mass of butane and multiply by 100. This gives you a mass percent of approximately 18.6%.
