Answer:
≈ 1833
Step-by-step explanation:
To find ratio of proton mass to electron mass, we have to divide.
The numbers are given in scientific notation.
Let a number be [tex]a*10^b[/tex] and another be [tex]c*10^d[/tex], when we divide, we will follow the rule shown below:
[tex]\frac{a*10^b}{c*10^d}=(\frac{a}{c}*10^{b-d})[/tex]
Now, we use the information given to find the ratio:
[tex]\frac{1.67*10^{-24}}{9.11*10^{-28}}\\=(\frac{1.67}{9.11}*10^{-24--28})\\=0.1833*10^4[/tex]
This means we can find the number by taking 4 decimal places to the right, so that would becomes:
[tex]0.1833*10^4=1833[/tex]
The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
Answer: The correct answer is D, 1833/1
