Carbon and Hydrogen Atoms in C2H4

The video tutorial explains how to determine the number of atoms in ethene (C2H4), a hydrocarbon. It starts by identifying the number of carbon and hydrogen atoms in a single molecule of C2H4. The tutorial then demonstrates how to calculate the number of carbon and hydrogen atoms in one mole of C2H4 using Avogadro's number, providing a clear example of multiplying the number of atoms by Avogadro's constant to find the total atoms in a mole.
