The sun is composed mostly of hydrogen. the mass of the sun is 2.0 * 10^30 kg, and the mass of a hydrogen atom is 1.67 * 10^-27 kg. estimate the number of atoms in the sun.

Mass of the sun (Ms= 2.0 * 10^30 kg)
mass of a hydrogen atom
( Ma = 1.67 * 10^-27 or 5/3 * 10^-27 kg)
number of atoms N = ... ?
N = Ms / Ma
= 2.0 * 10^30 / (5/3) * 10^-27
= 1.2 * 10^57 atoms
