The mass of a proton is approximately 1.67 x 10−24, and the mass of an electron is approximately 9.11 x 10−28. Find the approxim

nataly862011 [7]

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 $a*10^b$ and another be $c*10^d$ , when we divide, we will follow the rule shown below:

$\frac{a*10^b}{c*10^d}=(\frac{a}{c}*10^{b-d})$

Now, we use the information given to find the ratio:

$\frac{1.67*10^{-24}}{9.11*10^{-28}}\\=(\frac{1.67}{9.11}*10^{-24--28})\\=0.1833*10^4$

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

$0.1833*10^4=1833$

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
