Question 321027
The estimated masses of a proton and an electron are 1.67 x 10-24 grams and 9.11 x 10-28 grams, respectively. Find the ratio to three significant digits of the mass of the proton to the mass of the electron.
:
{{{(1.67(10^-24))/(9.11(10^-28))}}} = {{{(1.67(10^(-24+28)))/(9.11)}}} = .183315(10^4) = 1833.15
:
Proton mass is about 1833 times an electron mass
