Chemical Composition of Butane

The video tutorial explains how to determine the number of atoms in butane (C4H10). It begins by identifying the elements in C4H10, which are carbon and hydrogen, and calculates the total number of atoms in a molecule of butane. The tutorial then explains how to find the number of atoms in one mole of C4H10 using Avogadro's number. The video concludes with a summary of the calculations.
