Final answer:
The mass of an oxygen atom is approximately 159.76 times the mass of a hydrogen atom, which can be expressed as 1.60 x 10^2 in scientific notation.
Step-by-step explanation:
To find how many times the mass of the hydrogen atom is the mass of the oxygen atom, we divide the mass of an oxygen atom by the mass of a hydrogen atom. Given that the mass of a hydrogen atom is approximately 1.66 x 10^-25 grams and the mass of an oxygen atom is approximately 2.65 x 10^-23 grams, we perform the following calculation:( 2.65 x 10^-23 grams) / (1.66 x 10^-25 grams) = 1.597590361 x 10^
Therefore, the mass of an oxygen atom is approximately 159.76 times the mass of a hydrogen atom when rounded to two decimal places. We express this as 1.60 x 10^2 in scientific notation.
To determine how many times the mass of the hydrogen atom is the mass of the oxygen atom, we can divide the mass of oxygen by the mass of hydrogen:
2.65 x 10-26 kg / 1.66 x 10-27 kg = 1.6 x 101
Therefore, the mass of the oxygen atom is approximately 16 times the mass of the hydrogen atom.
