Answer: [tex]1.9 * 10^{-10}[/tex]
Step-by-step explanation:
The answer of this question is asking you to find the length of a hydrogen atom. You can find this by multiplying the diameter of a proton by the relationship between a hydrogen atom and a proton, as such:
[tex](1.9 * 10^{-15} ) * (1*10^5)[/tex]
You can ignore the coefficients (1.9 and 1) for the time being, but it's important to focus on the degrees. To multiply degrees, you can add the degrees of identical bases (in this case, 10).
[tex]10^{-15 + 5}[/tex]
So, part of your answer is [tex]10^{-10}[/tex].
You can retain the 1.9 coefficient from earlier to reach your final answer.
