$m=9.1xx10^-28g$

well...if you use your data you get:
$1.76xx10^8=(1.6xx10^-19)/m$
so $m=(1.6xx10^-19)/(1.76xx10^8)=9.1xx10^-28g$

What is the mass of electron if the charge of electron and the ratio of charge to mass are 1.6*10^(-19)"C"1.6*10^(-19)"C" and 1.76*10^8"C/g"1.76*10^8"C/g" , respectively?
