The mass of the Sun is 2.0 *10³⁰ kg, and the mass of a hydrogen atom is 1.67 *10^-²⁷ kg. If we assume that the Sun is mostly composed of hydrogen, how many atoms are there in the Sun? A) 1.2 * 10⁵⁶ atoms B) 3.4 * 10⁵⁶ atoms C) 1.2 * 10⁵⁷ atoms D) 2.4 * 10⁵⁷ atoms

Question

Quizplus · Accepted Answer

To find the number of hydrogen atoms in the Sun, divide the mass of the Sun by the mass of a hydrogen atom: (2.0 x 10^30 kg) / (1.67 x 10^-27 kg/atom) = 1.2 x 10^57 atoms.

The Mass of the Sun Is 2
