Question

An atom of hydrogen has a mass of about 1.66 x 10-²⁵ grams. An atom of oxygen has a mass of about 2.656 x 10-²³ grams. How many times the mass of the hydrogen atom is the mass of the oxygen atom?

Answer 1

The mass of an oxygen atom is 160 times the mass of a hydrogen atom.

Step-by-step explanation:

The mass of an atom of hydrogen is 1.66 x 10-25 grams, while the mass of an atom of oxygen is 2.656 x 10-23 grams. To find out how many times the mass of the oxygen atom is the mass of the hydrogen atom, we can divide the mass of oxygen by the mass of hydrogen.

2.656 x 10-23 grams / 1.66 x 10-25 grams = 160

Therefore, the mass of the oxygen atom is 160 times the mass of the hydrogen atom.
