The video tutorial explains how to determine the number of atoms in lithium hydroxide (LiOH). It begins by identifying the element symbols for lithium, oxygen, and hydrogen. The tutorial then explains how to count the atoms in LiOH, assuming a subscript of one for each element. It further discusses calculating the number of atoms in one mole of LiOH using Avogadro's number. Finally, the video covers the concept of hydroxide ions in LiOH, emphasizing the presence of one hydroxide ion in the compound.
