The Sun’s mass is 1.99×10^30kg, three-quarters of which is hydrogen. The mass of a hydrogen atom is 1.67× 10^-27kg. How many hydrogen atoms does the Sun contain? Use powers-of-ten notation.

Answer:
The Sun's hydrogen mass is (3/4) χ (1.99 χ 1030 kg) = 1.49 χ 1030 kg. Now divide the Sun's hydrogen mass by the mass of one hydrogen atom to get the number of hydrogen atoms contained in the Sun: (1.49 χ 1030 kg) / (1.67 χ 10-27 kg/atom) = 8.92 χ 1056 atoms.
