Answer:
5.403 x 10^21 protons
Step by step solved:
The atomic number of lithium is 3, which means that every lithium atom has 3 protons.
To determine the total number of protons in 1.801 x 10^21 lithium atoms, we simply need to multiply the number of atoms by the number of protons per atom:
Total number of protons = (1.801 x 10^21 atoms) x (3 protons/atom)
Total number of protons = 5.403 x 10^21 protons
Therefore, there are approximately 5.403 x 10^21 protons in 1.801 x 10^21 lithium atoms.
