By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' Atomic Mass is 31.0 grams

How many atoms are there along a 1 cm line?
Approximately 100,000,000. This assumes the atoms are one Angstrom apart, which is actually a little closer than you can pack most of them; for larger atoms, half of that would be a reasonable number.
How big would it be if you had a googolplex of atoms?
There are fewer than a googol atoms in the known universe so a googolplex atoms would be outrageously huge.
What is a shape with googolplexian sides called?
There is no such number. In any case, you would not be able to distinguish it from a circle since there are far fewer atoms in the universe than the number of vertices that such a figure would have. I would settle for calling it a googolplexian-gon.
If you could count two atoms every second how many years would it take you to count a mole of atoms?
There are 6.022x10^23 atoms in a mole. First, you should find the amount of seconds in a proper year (365.25 days). Then, halve the amount of atoms in the mole (because we are counting two per second), then simply divide this number by how many seconds in a year.
What is the number of particles in the universe?
It is estimated that there are 10^12 galaxies in the universe, each with about 10^12 stars. Each star has an average of 10^57 hydrogen atoms; using these estimates, the number of particles in the universe would be about 10^82.
