Question 135

An electrons mass is approximately $9.1093826\times {10}^{-31}$ kilograms. What is its mass in grams?

Answer 1

Mass of electron = $9.1093826\times {10}^{-31}kg$
= $9.1093826\times {10}^{-31}\times 1000g[\because 1kg=1000g]$
$=9.1093826\times {10}^{-31}\times {10}^3=9.1093826\times {10}^{-28}g[\because a^m\times a^n=a^{m+n}]$
