How do you calculate number of atoms?
So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply the given mass by the reciprocal of the molar mass. This is Mass → Moles . Once you have moles, multiply by Avogadro’s number to calculate the number of atoms. This is Moles → Atoms .

What is the number of atoms in the universe?
So again, if we assume that our galaxy is average, we get that the number of atoms in the universe is about 2.4 × 10 67 × 10 11 = 2.4 × 10 78. Internet research gives answers of around This number generally surprises people as they tend to expect it to be a lot bigger.
How many atoms are there in the Sun?
The Sun contains approximately 1057 atoms of hydrogen. If you multiple the number of atoms per star (1057) times the estimated number of stars in the universe (1023), you get a value of 1080 atoms in the known universe.
